My face or yours? Event-related potential correlates of self-face processing

The neural basis of self-recognition is mainly studied using brain-imaging techniques which reveal much about the localization of self-processing in the brain. There are comparatively few studies using EEG which allow us to study the time course of self-recognition. In this study, participants monitored a sequence of images, including 20 distinct images of their own face, a friend’s face and a stranger’s face articulating different speech sounds, while EEG was recorded from 64 scalp electrodes. Differences in the ERP waveforms were observed very early on, with increased N170 and VPP amplitude to self relative to both friend and stranger measured over posterior and fronto-central sites, respectively. This ‘self effect’ was also marked at ∼250 ms where P2/N2 amplitude was significantly reduced for self-faces. By comparison, differences between friend and stranger faces did not emerge until 250 ms and beyond, where a more conventional ‘familiarity effect’ was observed. The data also point to a ‘less lateralized’ representation of self over posterior sites. These findings are consistent with both behavioral and fMRI studies which suggest that self-face processing is ‘special’ and are discussed with reference to EEG studies of face processing.     

Effect of Item Level Social Desirability on Factor Structure Stability

This study examined the effect of item‐level social desirability as a threat to construct validity for both a five‐factor biodata and personality inventory. Seven hundred and five participants were randomly assigned to either an Answer Honestly or Faking condition. All participants completed a biodata inventory and a NEO‐Five‐Factor Inventory. Both inventories' items were divided by low/high social desirability value (SDV) scores and grouped together. Differences between samples' covariance matrices and factor structure fit were then analyzed. It was predicted that items grouped by low SDV compared with those grouped by high SDV, would result in smaller changes in covariance matrices across conditions, and more closely retain factor structures consistent with the Five‐Factor Model. Although the results of this study supported predictions that covariance matrices changed less for low‐SDV items, overall results indicate that item‐level social desirability did not degrade the factor structure.     

Interaction between the development of postural control and the executive function of attention

The authors examined the interaction between the development of postural control and the development of the executive function of attention in 13 children and 6 adults in dual-task conditions. Participants performed an attentionally demanding cognitive task and a postural task simultaneously. The authors equalized the attentional load of the cognitive task across age groups. Comparative changes in the center of pressure in dual- and single-task conditions indicated that dual tasks interfered with postural performance in the wide stance (WS) and the modified Romberg stance (RS). Children at 4-6 years of age (but not children at ages 7-12 years of age or adults) experienced postural control interference in both stance positions, but interference was greater in the RS (p = .018). For all participants, cognitive task performance in RS was unchanged from that in WS. The knowledge gained from the results of this study will contribute to the design and implementation of academic and preacademic programming for young children. Their performance of an intentionally demanding cognitive task would be enhanced by the provision of appropriately sized desks and chairs or their use of an alternate, less demanding position.     

Training Appraisees to Participate in Appraisal: Effects on Appraisers and Appraisees

This study examined the role of behavior modeling training (BMT) in enhancing appraisee participation during a performance appraisal discussion. In addition, the study examined the effects of enhanced participation on appraisee and appraiser perceptions toward several appraisal outcome variables; in particular, the fairness and accuracy of performance appraisal were of interest. The experimental design was a 2 × 3 completely crossed factorial design consisting of two levels of training (behavior modeling vs. lecture/discussion) and three levels of bogus evaluation feedback (low, neutral, and high). A series of multivariate and univariate comparisons were used to test the hypothesized outcomes. The findings suggest that appraisers exposed to the BMT group perceived appraisees as more proactive and better performers and, in addition, reported liking the appraisees more, and perceiving the appraisal process as more fair. The study also found support for the egocentric bias in perceived outcome fairness: appraisees in both training conditions who received a high evaluation perceived the appraisal evaluation as more fair than appraisees who received a low evaluation. In addition, the study found that favorable evaluations were also perceived as being more accurate. The results of the study are discussed in terms of procedural justice theory and related research examining the role of performance feedback on both the appraisee and the appraiser. Suggestions for future research in the areas of behavior modeling, voice-giving (high-input) procedures, and procedural justice are discussed.     

Program evaluation and system change: Some issues and considerations

This paper explores some of the issues concerning the acceptance or rejection of positive program evaluation data by the system in which the program is embedded. System acceptance and diffusion rates are considered as functions of first- or second-order change factors. Several approaches to enhancing the probability of second-order change are presented and discussed.     

When logic fails: Implicit transitive inference in humans

Transitive inference (TI) in animals (e.g., choosing A over C on the basis of knowing that A is better than B and B is better than C) has been interpreted by some as reflecting a declarative logical inference process. We invert this anthropomorphic interpretation by providing evidence that humans can exhibit TI-like behavior on the basis of simpler associative mechanisms that underlie many theories of animal learning. In this study, human participants were trained on a five-pair TI problem (A+B-, B+C-, C+D-, D+E-, E+F-) and, unlike in previous human TI studies, were prevented from becoming explicitly aware of the logical hierarchy, so they could not employ logical reasoning. They were then tested with three problems: B versus D, B versus E, and C versus E. Participants only reliably chose B over E, whereas the other test conditions yielded chance performance. This result is inconsistent with the use of logical reasoning and is instead consistent with an account developed to explain earlier TI studies with rats that found the same pattern of results. In this account, choice performance is based on differential associative strengths across the stimulus items that develop over training, despite equal overt reinforcement.     

Reasonable accommodation for employees with mental disabilities: a mandate for effective supervision?

Reasonable accommodation under Title I of the Americans with Disabilities Act (ADA) for employees with mental disabilities is explored from a behavior analytic perspective. Although much of the attention in issues of reasonable accommodation is concentrated on persons with physical disabilities, it is argued that the needs of individuals with mental disabilities are in greater need of further study. The criteria for successful accommodation in the workplace for employees with mental disabilities is seen to be structurally different, but functionally similar to successful accommodations for employees with physical disabilities, and is based on the development of enabling environments. Behavior analysis offers a theoretical basis and performance management presents a methodological basis for analyzing, developing, implementing, and evaluating reasonable accommodation for persons with mental disabilities, largely in terms of effective supervision. It is concluded that Title I of the ADA may be seen as providing a mandate for effective supervision, which may also be extended to all employees.     

Cognitive vulnerability to depression: A comparison of the weakest link,keystone and additive models

Multiple theories of cognitive vulnerability to depression have been proposed, each focusing on different aspects of negative cognition and utilising different measures of risk. Various methods of integrating such multiple indices of risk have been examined in the literature, and each demonstrates some promise. Yet little is known about the interrelations among these methods, or their incremental validity in predicting changes in depression. The present study compared three integrative models of cognitive vulnerability: the additive, weakest link, and keystone models. Support was found for each model as predictive of depression over time, but only the weakest link model demonstrated incremental utility in predicting changes in depression over the other models. We also explore the correlation between these models and each model's unique contribution to predicting onset of depressive symptoms.
