Vision And Language

In this review we focus on the close interplay between visual contextual information and real-time language processing. Crucially, we are showing that not only college-aged adults but also children and older adults can profit from visual contextual information for language comprehension. Yet, given age-related biological and experiential changes, children and older adults might not always be able to link visual and linguistic information in the same way and with the same time course as younger adults in real-time language processing. Psycholinguistic research on visually situated real-time language processing in children and even more so older adults is still scarce compared to research in this domain using college-aged participants. In order to gain more comprehensive insights into the interplay between vision and language during real-time processing, we are arguing for a lifespan approach to situated language processing.

The Relationship

To achieve an appropriate level of reliance on an automated system, the operator must have an accurate system representation such that he/she is aware of the capabilities and limitations of the system. The appropriate use of an automated system can lead to optimal performance by the human-machine dyad. This study investigates the relationship between an accurate system representation and behaviors associated with human-automation interaction (e.g., reliance). Furthermore, age-related effects are also included in the investigation. A cooking memory aid (Cook's Collage) is used as an automated aid that keeps track of the ingredients used in a specific recipe. Participants are asked to interact with the automated device for 5 sessions (each on different days). Tasks are structured to simulate those in a real kitchen. Preliminary results suggest that that there is a different pattern of interaction with the aid as a function of age. Older adults tend to rely on the aid for real-time feedback while younger adults use the aid as a verification tool that they have executed the recipe as desired.

Tip Of The Tongue

The Speech-to-Song Illusion is an auditory illusion that occurs when a spoken phrase is repeatedly presented. After several presentations, listeners report that the phrase seems to be sung rather than spoken. Previous work [1] indicates that the mechanisms—priming, activation, and satiation—found in the language processing model, Node Structure Theory (NST), may account for the Speech-to-Song Illusion. NST also accounts for other language-related phenomena, including increased experiences in older adults of the tip-of-the-tongue state (where you know a word, but can’t retrieve it). Based on the mechanism in NST used to account for the age-related increase in the tip-of-the-tongue phenomenon, we predicted that older adults may be less likely to experience the Speech-to-Song Illusion than younger adults. Adults of a wide range of ages heard a stimulus known to evoke the Speech-to-Song Illusion. Then, they were asked to indicate if they experienced the illusion or not (Study 1), to respond using a 5-point song-likeness rating scale (Study 2), or to indicate when the percept changed from speech to song (Study 3). The results of these studies suggest that the illusion is experienced with similar frequency and strength, and after the same number of repetitions by adult listeners regardless of age.

The dual mechanisms of control framework proposes that age-related declines in cognitive control are due to deficits with continuous goal maintenance (proactive control). Older adults default instead to another form of control (reactive control). In contrast to these declines, older adults demonstrate preserved emotional processing. According to the socioemotional selectivity theory, perceived time constraints related to advancing age results in emotional regulation goals in which older adults prioritize positive well-being or mood. To achieve this, they devote more cognitive resources and pay greater attention to positive versus negative information (“positivity effects”) than younger adults. Research on the interactions between cognitive control and emotion is increasing but work focused on the interactions in older adults is limited. Thus, it is unknown how older adults' emotional goals may influence their goal maintenance deficits. This study manipulated mood and emotional face stimuli to examine whether these factors affect age differences in cognitive control between younger (ages 18-30) and older adults (ages 65+). Experiment 1 induced neutral or negative moods prior to a cognitive control task (the standard letter AX-CPT task). Results indicated typical patterns of proactive control in younger adults and reactive control in older adults that did not vary substantially by mood. Experiment 2 examined the effects of neutral, negative, and positive mood inductions on a less cognitively demanding version of the AX-CPT (with face cues as contextual information). Results showed evidence of enhanced proactive control in older adults that was comparable to that of younger adults across all mood conditions, although this was limited to response time data. Additionally, there was evidence of small mood effects on cognitive control. Finally, Experiment 3 examined the effect of positive, negative, and neutral contextual information (face cues) on older adults' cognitive control performance using a different variant of the AX-CPT (face AX-CPT). Results indicated strong engagement in reactive control that did not vary by the emotionality of the contextual information. Together, the results of this study suggest that older adults’ proactive control patterns are affected by the task demands of the AX-CPT, but there is less evidence of mood or emotional stimuli effects.

Cognitive Task Performance

Motivational incentives play an influential role in value-based decision-making and cognitive control. A compelling hypothesis in the literature suggests that the brain integrates the motivational value of diverse incentives (e.g., motivational integration) into a common currency value signal that influences decision-making and behavior. To investigate whether motivational integration processes change during healthy aging, we tested older (N=44) and younger (N=54) adults in an innovative incentive integration task paradigm that establishes dissociable and additive effects of liquid (e.g., juice, neutral, saltwater) and monetary incentives on cognitive task performance. The results reveal that motivational incentives improve cognitive task performance in both older and younger adults, providing novel evidence demonstrating that age-related cognitive control deficits can be ameliorated with sufficient incentive motivation. Additional analyses revealed clear age-related differences in motivational integration. Younger adult task performance was modulated by both monetary and liquid incentives, whereas monetary reward effects were more gradual in older adults and more strongly impacted by trial-by-trial performance feedback. A surprising discovery was that older adults shifted attention from liquid valence toward monetary reward throughout task performance, but younger adults shifted attention from monetary reward toward integrating both monetary reward and liquid valence by the end of the task, suggesting differential strategic utilization of incentives. Together these data suggest that older adults may have impairments in incentive integration, and employ different motivational strategies to improve cognitive task performance. The findings suggest potential candidate neural mechanisms that may serve as the locus of age-related change, providing targets for future cognitive neuroscience investigations.

Objective: Online banking is becoming increasingly common among older adults, whomay experience difficulties effectively navigating this instrumental technology. Thisstudy examined age effects on a performance-based Internet banking task and itsassociation with neurocognitive ability and functional capacity in older and youngeradults. Method: Thirty-five older adults and 50 younger adults completed anexperimenter-controlled online banking measure in which they independentlyperformed a series of naturalistic financial tasks (e.g., account transfers, bill paying).Participants also completed a standardized battery of neuropsychological tests andmeasures of functional capacity. Results: Older adults were markedly slower and lessaccurate in completing the Internet-based banking task, which was not confounded byother demographic, mood, or computer use factors. Higher scores on measures ofneurocognition and financial functional capacity were both strongly associated withhigher Internet-based banking task accuracy scores and quicker completion times inthe older, but not the younger adults. Conclusions: Findings suggest that older adultsexperience difficultly quickly and accurately navigating online banking platforms, whichmay be partly related to age-related declines in neurocognitive functions and basicfinancial capacity. Future studies might examine whether neurocognitive approaches toremediation and compensation can be used to improve online banking capacity inolder adults.

Different Levels

The study of cognitive phenomena is best approached in an orderly manner. It must begin with an analysis of the function in intension at the heart of any cognitive domain (its knowledge base), then proceed to the manner in which such knowledge is put into use in real-time processing, concluding with a domain’s neural underpinnings, its development in ontogeny, etc. Such an approach to the study of cognition involves the adoption of different levels of explanation/description, as prescribed by David Marr and many others, each level requiring its own methodology and supplying its own data to be accounted for. The study of recursion in cognition is badly in need of a systematic and well-ordered approach, and this chapter lays out the blueprint to be followed in the book by focusing on a strict separation between how this notion applies in linguistic knowledge and how it manifests itself in language processing.

Reference Processing

Abstract This study examines the use of discourse-level information to create expectations about reference in real-time processing, testing whether patterns previously observed among native speakers of English generalize to nonnative speakers. Findings from a visual-world eye-tracking experiment show that native (L1; N = 53) but not nonnative (L2; N = 52) listeners’ proactive coreference expectations are modulated by grammatical aspect in transfer-of-possession events. Results from an offline judgment task show these L2 participants did not differ from L1 speakers in their interpretation of aspect marking on transfer-of-possession predicates in English, indicating it is not lack of linguistic knowledge but utilization of this knowledge in real-time processing that distinguishes the groups. English proficiency, although varying substantially within the L2 group, did not modulate L2 listeners’ use of grammatical aspect for reference processing. These findings contribute to the broader endeavor of delineating the role of prediction in human language processing in general, and in the processing of discourse-level information among L2 users in particular.

Optimal Functioning

Abstract Intensive measurements of individuals’ experiences allow for identifying patterns of functioning that may be markers of resilience, and whether such patterns differ across the life span. Using 8 daily diary reports collected in the second burst of the National Study of Daily Experiences (NSDE, n=848, age 34-84; 55%female), we examined whether positive emodiversity (Shannon’s entropy) attenuated the association between cumulative stressor exposure and depressive symptoms, and age-related differences therein. Results indicated age moderated the extent to which positive emodiversity attenuated the association between stress and depressive symptoms (b=0.11, p < .05). The attenuated association was strongest for younger adults with higher positive emodiversity, compared to those with lower positive emodiversity. For older adults, the association between stress and depressive symptoms was relatively similar regardless of their positive emodiversity. Implications pertain to for whom and in what contexts specific types of dynamic emotion experiences may promote optimal functioning and resilience.

Effect Of Age

Vibrotactile feedback (VTF) has been shown to improve balance performance in healthy people and people with vestibular disorders in a single-task experimental condition. It is unclear how age-related changes in balance affect the ability to use VTF and if there are different attentional requirements for old and young adults when using VTF. Twenty younger and 20 older subjects participated in this two-visit study to examine the effect of age, VTF, sensory condition, cognitive task, duration of time, and visit on postural and cognitive performance. Postural performance outcome measures included root mean square of center of pressure (COP) and trunk tilt, and cognitive performance was assessed using the reaction time (RT) from an auditory choice RT task. The results showed that compared with younger adults, older adults had an increase in COP in fixed platform conditions when using VTF, although they were able to reduce COP during sway-referenced platform conditions. Older adults also did not benefit fully from using VTF in their first session. The RTs for the secondary cognitive tasks increased significantly while using the VTF in both younger and older adults. Older adults had a larger increase compared with younger adults, suggesting that greater attentional demands were required in older adults when using VTF information. Future training protocols for VTF should take into consideration the effect of aging.
