From eyes to hands: Transfer of learning in the Simon task across motor effectors

Inhibition of irrelevant and conflicting information and responses is crucial for goal-directed behaviour and adaptive functioning. In the Simon task, for example, responses are slowed if their mappings are spatially incongruent with stimuli that must be discriminated on a nonspatial dimension. Previous work has shown that practice with incongruent spatial mappings can reduce or even reverse the Simon effect. We asked whether such practice transfers between the manual and oculomotor systems and if so to what extent this occurs across a range of behavioural tasks. In two experiments, one cohort of participants underwent anti-saccade training, during which they repeatedly inhibited the reflexive impulse to look toward a briefly presented target. Additionally, two active-control training groups were included, in which participants either trained on Pro-saccade or Fixation training regimens. In Experiment 1, we probed whether the Simon effect and another inhibitory paradigm, the Stroop task, showed differential effects after training. In Experiment 2, we included a larger battery of inhibitory tasks (Simon, Stroop, flanker and stop-signal) and noninhibitory control measures (multitasking and visual search) to assess the limits of transfer. All three training regimens led to behavioural improvements in the trained-upon task, but only the anti-saccade training group displayed benefits that transferred to the manual response modality. This transfer of training benefit replicated across the two experiments but was restricted to the Simon effect. Evidence for transfer of inhibition training across motor systems offers important insights into the nature of stimulus-response representations and their malleability.     

Age-related similarities and differences in first impressions of trustworthiness

Trust is a particularly under-studied aspect of social relationships in older age. In the current study, young (n = 35) and older adults (n = 35) completed a series of one-shot social economic trust games in which they invested real money with trustees. There were potential gains with each investment and also a risk of losing everything if the trustee was untrustworthy. The reputation and facial appearance of each trustee were manipulated to make them appear more or less trustworthy. Results revealed that young and older adults invest more money with trustees whose facial appearance and reputation indicate that they are trustworthy rather than untrustworthy. However, older adults were more likely than young to invest with trustees who had a reputation for being untrustworthy. We discuss whether age-related differences in responding to negative information may account for an age-related increase in trust, particularly when trusting someone with a reputation for being uncooperative.     

The relationship between prospective memory and episodic future thinking in younger and older adulthood

Episodic future thinking (EFT), the ability to project into the future to “preexperience” an event, and prospective memory (PM), remembering to perform an intended action, are both examples of future-oriented cognition. Recently it has been suggested that EFT might contribute to PM performance but to date few studies have examined the relationship between these two capacities. The aim of the present study was to investigate the nature and specificity of this relationship, as well as whether it varies with age. Participants were 125 younger and 125 older adults who completed measures of EFT and PM. Significant, positive correlations between EFT and PM were identified in both age groups. Furthermore, EFT ability accounted for significant unique variance in the young adults, suggesting that it may make a specific contribution to PM function. Within the older adult group, EFT did not uniquely contribute to PM, possibly indicating a reduced capacity to utilize EFT, or the use of compensatory strategies. This study is the first to provide systematic evidence for an association between variation in EFT and PM abilities in both younger and older adulthood and shows that the nature of this association varies as a function of age.     

The perception of emotionally toned sentences by right hemisphere-damaged and aphasic subjects

The perception of 60 emotionally toned sentences, divided into meaningful and meaningless utterances, by high- and low-verbal aphasics and right hemisphere-damaged subjects who were not aphasic was investigated. The intended moods were happiness, sadness, and anger. Results indicated (a) significant differences between the aphasic groups in identifying the intended emotion but none between groups in identifying the intended emotion but none between either of these groups and the right hemispheric dysfunction subjects; (b) sentence meaningfulness only affected the responses of high-verbal aphasics; and (c) while the happy mood seemed to be the least frequently selected among the three moods, closer inspection indicated that the subjects in absence of response bias were distinguishing among the three moods with equal success.     

Some effects of gaze on subjects motivated to seek or to avoid social comparison

In a conceptual replication and extension of Sarnoff and Zimbardo's study (Journal of Abnormal and Social Psychology, 1961, 62, 356–363), subjects were motivated to seek (Fear Arousal) or avoid (Embarrassment Arousal) social comparison. They were then required to affiliate with another person who either encouraged social comparison by gazing directly at the subject or discouraged it by averting his gaze. This other person was either an appropriate reference person (similar saate) or irrelevant for social comparison purposes. As predicted, Fear subjects liked a companion who looked at them and felt less tense in his presence, while Embarrassed subjects preferred the person who looked away. This interaction occurred only in the Appropriate Reference Person condition, a result consistent with an explanation based on social comparison processes.     

Predictors and Outcomes of Sudden Gains and Sudden Regressions in Cognitive Behavioral Therapy for Youth Anxiety

Sudden gains (SGs), referring to large, stable symptom improvement occurring between consecutive treatment sessions, have been associated with improved outcomes among adults with various psychological disorders. Little research exists on SGs or sudden symptom worsening (i.e., sudden regressions [SRs]) during treatment for youth disorders. The current study examined predictors and outcomes of SGs/SRs via multiple informants in youth anxiety treatment. Participants were 118 youth (age M = 11.6, SD = 2.5; 53.8% female) and their caregivers receiving a cognitive-behavioral therapy protocol for a principal anxiety disorder. Anxiety symptom severity was assessed weekly via the State-Trait Anxiety Inventory for Children–Trait–Child/Parent versions. SGs and SRs occurred in 45.8 and 31.3% of youth, respectively. SRs were more common among youth with comorbid mood or externalizing disorders, while SGs occurred more often among youth with greater pretreatment anxiety symptom severity. SGs were not associated with posttreatment outcomes, but SRs predicted significantly higher posttreatment internalizing symptoms based on child report (β = .23, p = .03) and externalizing symptoms based on child (β = .15, p = .04) and parent report (β = .16, p = .03), controlling for overall magnitude of symptom change. SRs among youth receiving cognitive-behavioral therapy for anxiety are associated with pretreatment clinical complexity and poorer posttreatment outcomes and may serve as a warning sign to clinicians of possible treatment failure.     

Disability as diversity in Fortune 100 companies

To investigate the inclusion of people with disabilities in the diversity policies of the most successful businesses in the United States, we examined the publicly available workforce and supplier diversity policies of the top 100 companies on Fortune Magazine's 2003 list of the 500 most profitable companies in the nation. The majority of these companies have extensive information about their diversity policies and practices available on their corporate website. The information was used to categorize the policies into those that include people with disabilities, do not define diversity, and enumerate what is meant by diversity (e.g. in terms of race or gender) but do not expressly mention disability. In addition, we looked beyond the diversity policies to information available on corporate websites relating to a variety of diversity initiatives. Findings suggest that the majority of the companies that top the Fortune 500 list have developed and implemented diversity policies. Of these, 42% have diversity policies that include people with disabilities in the definition of a diverse workforce. Furthermore, 47% of companies with workplace diversity policies discuss diversity in a way that neither expressly includes nor excludes people with disabilities. Far fewer (15%) supplier diversity policies include disability in the definition of diversity, but a significant number of companies use criteria that allow a business owner with a disability to benefit from the company's supplier diversity program.
