EXPANDING THE IMPACT OF BEHAVIORAL STAFF MANAGEMENT: A LARGE-SCALE,LONG-TERM APPLICATION IN SCHOOLS SERVING SEVERELY HANDICAPPED STUDENTS

Experimental evaluations of behavioral staff management procedures usually have been limited to relatively small-scale demonstration studies. We evaluated a large-scale, long-term application of a staff management program designed to improve the functional utility of educational services for severely handicapped persons. The intervention, involving a brief in-service program followed by supervisory prompts and feedback, was implemented by three principals in four schools involving 21 classrooms. Implementation of the management procedures was consistently accompanied by increases in student involvement in functional educational tasks in each classroom. Further, the improved services continued throughout a 2-year follow-up period. Staff responses to a questionnaire indicated a high degree of staff acceptance of the management program. Results are discussed in terms of expanding the use of behavioral supervisory procedures from experimental demonstrations to actual adoption by existing human service agencies.     

Differential reinforcement of low rates of responding (DRL) to reduce dysfunctional social behaviors of a head injured man

Differential reinforcement of low rates of responding (DRL) is a technique in which a positive reinforcer is delivered at the end of a specific interval if a target behavior has occurred at a criterion rate. Traditionally, it has been used in educational settings to manage classroom behaviors. Recently, therapists have begun to use DRL to reduce the rates of a variety of behaviors in non-educational settings. In this study, DRL was part of a behavioral intervention to reduce dysfunctional verbal and physical behaviors of a head-injured young man. The complete intervention program included DRL, changing criteria, and token reinforcement. Over a period of 15 weeks, the intervention resulted in reductions in behaviors in both categories from high rates to near-zero rates.     

The Effects of Truth–Lie Base Rate on Interactive Deception Detection Accuracy

Consistent with the Park and Levine's (PL) probability model of deception detection accuracy, previous research has shown that as the proportion of honest messages increases, there is a corresponding linear increase in correct truth–lie discrimination. Three experiments (N = 120, 205, and 243, respectively) varied the truth–lie base rate in an interactive deception detection task. Linear base‐rate effects were observed in all 3 experiments (average effect r#x02009;= .61) regardless of whether the judges were interactive participants or passive observers, previously acquainted or strangers, or previously exposed to truths or lies. The predictive power of the PL probability model appears robust and extends to interactive deception despite PL's logical incompatibility with interpersonal deception theory.     

Just between us: Exclusive communications in online social networks

Social media websites such as Facebook are used for relationship development and maintenance often through self-disclosure and sharing of personal information. However, not all forms of social media communication may be equally suitable for this task. This paper explores users’ norms about the appropriateness of using private vs. public Facebook messages to communicate different kinds of personal information, and the effectiveness of these types of communication in building relationships. Study 1, a survey, revealed that users endorse conflicting expectations about preferences for receiving information publicly or privately. Study 2, a field experiment testing the effects of private versus public Facebook communications on actual relationship development using participants’ own Facebook pages, suggested that private messages lead to greater closeness.     

Neuroethical and Social Implications of Using Transcranial Electrical Stimulation to Augment Creative Cognition

Recent research indicates that transcranial electrical stimulation (tES) of specific brain regions can successfully improve various forms of creative cognition. Although the endeavor to increase human creative capacity is intriguing from a neuroscientific perspective, and of interest to the general public, it raises numerous neuroethico-legal and social issues (NELSI). This review explores these issues by considering (a) whether using brain stimulation to improve creative cognition qualifies as a ‘treatment’ or an ‘enhancement,’ (b) how direct-to-consumer (DTC) and do-it-yourself (DIY) use of tES should be regarded and regulated, and (c) what the developing landscape of creativity-related neurostimulation could (and should) become.     

Factors contributing to individual differences in facial expression categorisation

Individuals vary in perceptual accuracy when categorising facial expressions, yet it is unclear how these individual differences in non-clinical population are related to cognitive processing stages at facial information acquisition and interpretation. We tested 104 healthy adults in a facial expression categorisation task, and correlated their categorisation accuracy with face-viewing gaze allocation and personal traits assessed with Autism Quotient, anxiety inventory and Self-Monitoring Scale. The gaze allocation had limited but emotion-specific impact on categorising expressions. Specifically, longer gaze at the eyes and nose regions were coupled with more accurate categorisation of disgust and sad expressions, respectively. Regarding trait measurements, higher autistic score was coupled with better recognition of sad but worse recognition of anger expressions, and contributed to categorisation bias towards sad expressions; whereas higher anxiety level was associated with greater categorisation accuracy across all expressions and with increased tendency of gazing at the nose region. It seems that both anxiety and autistic-like traits were associated with individual variation in expression categorisation, but this association is not necessarily mediated by variation in gaze allocation at expression-specific local facial regions. The results suggest that both facial information acquisition and interpretation capabilities contribute to individual differences in expression categorisation within non-clinical populations.
