Training intraverbal bidirectional naming to establish generalized equivalence class performances

The purpose of this study was to evaluate the effects of tact and intraverbal training on the establishment of generalized equivalence classes. Seventeen college students were exposed to tact training, listener testing, and intraverbal training (A'B’ and B'C’) in two experiments. Visual–visual matching‐to‐sample and intraverbal tests measured performances consistent with the formation of equivalence classes. Generalization was assessed with four novel sets of stimuli. In the second experiment, matching‐to‐sample tests for baseline relations (AB, BC) were eliminated to control for the possibility that equivalence classes were developed through exposure to these visual stimulus–stimulus relations. Thirteen of 17 participants passed all matching‐to‐sample and intraverbal posttests. Results suggest that when trained and emergent intraverbal relations were not maintained or were faulty, participants did not respond correctly during matching‐to‐sample posttests.     

The effects of differential training procedures on linked perceptual class formation

When the stimuli in one perceptual class (A') become related to the stimuli in another perceptual class (B'), the two are functioning as a single linked perceptual class. A common linked perceptual class would be the sounds of a person's voice (class A') and the pictures of that person (class B'). Such classes are ubiquitous in real world settings. We describe the effects of a variety of training procedures on the formation of these classes. The results could account for the development of naturally occurring linked perceptual classes. Two perceptual classes (A' and B') were formed in Experiment 1. The endpoints of the A' class were called anchor (Aa) and boundary (Ab) stimuli. Likewise, the anchor and boundary stimuli in the B' class were represented as Ba and Bb. In Experiment 2, the A' and B' classes were linked by the establishment of one of four cross-class conditional discriminations: Aa-->Ba, Aa-->Bb, Ab-->Ba, or Ab-->Bb. Results were greatest after Aa-->Bb training, intermediate after Aa-->Ba and Ab-->Ba training, and lowest after Ab-->Bb training. Class formation was influenced by the interaction of the anchor/boundary values and the sample/comparison functions of the stimuli used in training. Experiment 3 determined whether class formation was influenced by different sets of two cross-class conditional discriminations: Aa-->Ba and Ab-->Bb, or Aa-->Bb and Ab-->Ba. Both conditions produced equivalent results. Similarities were attributable to the use of anchor stimuli as samples and boundary stimuli as comparisons in each training condition. Finally, the results afterjoint Aa-->Ba and Ab-->Bb training were much greater than those produced by summing the results of Aa-->Ba training alone and Ab-->Bb training alone. This same synergy was not observed after joint Aa-->Bb and Ab-->Ba training or either alone.     

Three Questions Regarding the Ecological Validity of Experimental Research on the Impact of Viewing Thin-Ideal Media Images

We experimentally examined fairness perceptions of accommodating people with disabilities by manipulating the granting of an accommodation, reward structure, and the best performer on a word search task. Data from 134 undergraduate students indicated that granting an accommodation was seen as less fair than not granting it, that having a person with a disability excel in performance was seen as less fair than when the person did not excel, and that fairness perceptions were lowest when the person with a disability received an accommodation and excelled in performance. Although the intent of the Americans with Disabilities Act (ADA) is to level the playing field for people with disabilities, our results show that when an accommodation helps the requester, others think it is unfair.     

American Military Veteran Entrepreneurs: A Comprehensive Profile of Demographic,Service History,and Psychosocial Characteristics

American military veterans are nearly twice as likely to be self-employed compared with nonveterans and are majority owners in 9% of all businesses nationwide. Despite their contribution to the broader economy and the potential for training programs to cultivate and foster successful self-employment and veteran-lead entrepreneurial ventures, research on veteran entrepreneurs remains limited. To gain a better understanding of the potential strengths and vulnerabilities of veteran entrepreneurs, the current study utilized data from a large, nationally representative sample to profile self-employed veterans (n = 230) and compare them with veterans who work as employees (n = 1,055) with respect to demographic, military service history, and psychosocial characteristics. Results indicated that self-employed veterans were older and more educated and more likely to utilize U.S. Department of Veteran’s Affairs (VA) health care. Self-employed veterans were more likely to serve in Vietnam and to serve in the military for fewer years. No differences were noted in perceived military experience, level of combat exposure, or military branch served as a function of self-employment. Although reporting more lifetime traumas, self-employed veterans did not experience higher rates of current or lifetime psychopathology or lower perceived quality of life. Potential protective resilience-promoting factors may be associated with the higher levels of openness, extraversion, optimism, achievement-orientation (purpose in life), and greater need for autonomy and professional development observed among self-employed veterans. Moreover, self-employed veterans demonstrated higher levels of gratitude, community integration, and altruistic service to others. Findings have potential to inform human resources management strategies and vocational training and reintegration initiatives for veterans.     

Neurobehavioral Functioning in Children with Fetal Alcohol Spectrum Disorder

Neurobehavioral functioning of 50 Canadian children diagnosed with Fetal Alcohol Spectrum Disorder (FASD) was evaluated. The aims of this study were to identify specific areas of weakness in neurobehavioral functioning, to examine whether neurobehavioral functioning was related to various predictor variables, and to determine which measures differentiated between children given a brain score of 2 (possible dysfunction) and 3 (probable dysfunction). Participants displayed difficulties with many aspects of intelligence, memory, executive functioning, and attention. Measures of Full scale and Verbal IQ, as well as memory for faces and numbers differentiated between children with a brain 2 and 3 ranking. An interesting pattern of strengths and weaknesses emerged as well as significant differences related to ethnic background, gender, and age. Aboriginal children and Caucasian children with FASD do not appear to show the same pattern of strengths and weaknesses in neurobehavioral functioning.     

Discussion of “Unraveling Whiteness”: Commentary on Paper by Melanie Suchet

In this discussion I consider several influences on the contemporary project of deconstructing racism and the concept of racialized subjectivity. This discussion applauds the turn in Suchet's work toward self-examination in a consideration of the experience of race and racism. Suchet's work moves the debates about racialized subjectivities into a deeper and more complex understanding of all the ways in which identifications and attachments cross race and class lines for many individuals. This discussion focuses on Suchet's treatment of the power of hybridic and biracial identifications, beginning with autobiographical material from Suchet's own childhood in South Africa. In this discussion of “Unraveling Whiteness” I integrate psychoanalytic concepts of enigmatic signification (the work of Laplanche) into a discussion of early attachment, and relational configurations with children and nonparental caretakers. The question of trauma or potential transformation in interracial experience is discussed, and some distinctions between American and South African experience are considered.

In this response to Bromberg, I note the ways in which his commentary has further stimulated and enriched my thinking.
