Discriminative control of punished stereotyped behavior in humans

The purpose of this experiment was to establish discriminative control of responding by an antecedent stimulus using differential punishment because the results of past studies on this topic have been mixed. Three adults with mental retardation who exhibited stereotypy not maintained by social consequences (i.e., automatic reinforcement) participated. For each subject, stereotypy occurred frequently in the presence of a stimulus correlated with nonpunishment of stereotypy and rarely, if ever, in the presence of a stimulus correlated with punishment of stereotypy. Latency measures showed that the antecedent stimulus correlated with punishment served as the discriminative stimulus for the suppression of stereotypy. These results are important insofar as they show that discriminative control by an antecedent stimulus develops with punishment, and because it sometimes may be desirable to establish such control of socially inappropriate behavior.     

Qualitative differences between the joint effects of stimulus quality and word frequency in reading aloud and lexical decision: extensions to Yap and Balota (2007)

There have been multiple reports over the last 3 decades that stimulus quality and word frequency have additive effects on the time to make a lexical decision. However, it is surprising that there is only 1 published report to date that has investigated the joint effects of these two factors in the context of reading aloud, and the outcome of that study is ambiguous. The present study shows that these factors interact in the context of reading aloud and at the same time replicate the standard pattern reported for lexical decision. The main implication of these results is that lexical activation, at least as indexed by the effect of word frequency, does not unfold in a uniform way in the contexts reported here. The observed dissociation also implies, contrary to J. A. Fodor's (1983) view, that the mental lexicon is penetrable rather than encapsulated. The distinction between cascaded and thresholded processing offers one way to understand these and related results. A direction for further research is briefly noted.     

Asé and Amen,Sister!

At times, the academy seems devoid of justice because it emphasizes the cultivation of knowledge often denied to marginalized individuals and communities. As black queer feminist scholars doing praxis‐driven theorizing from separate fields on the subject of black queer families and communities, we employ research methods that resist the dynamics of power and privilege that exist within normative researcher‐participant exchanges. In this essay, we explore and highlight the ethical, justice‐oriented, and dialogical relationship between researcher‐scholars and research participants. Through story and theory, we illustrate and argue that autoethnographies and narrative interviews can act as epistemological excavation tools for both researchers and participants, as they become sites of individual and collective consciousness. Our work resists capitalist models of research and instead promotes a justice‐oriented and community‐derived building of knowledge.     

Sex-Dimorphic Color Preference in Children with Gender Identity Disorder: A Comparison to Clinical and Community Controls

The present study was designed to assess sex-dimorphic color preferences in children with gender identity disorder (47 boys, 18 girls), clinical controls (65 boys, 35 girls), and community controls (65 boys, 35 girls). The mean age of the children was 7.63 years (range?=?3–12 years). Children were shown a hexagon-shaped display of 144 colors extracted from PowerPoint?. Each child was asked to choose his or her three favorite colors (Trials 1–3) by pointing to them, naming them, and then to provide a justification for each choice. From the entire array, children labeled a total of 11 different colors: black, blue, brown, gray, green, orange, pink, purple, red, white, and yellow. For three of the colors (blue, pink/purple, and red), there was evidence for normative sex differences in color preference, and, for the colors blue and pink/purple, the gender-referred children showed inverted patterns of color preference. For the color blue, luminance values showed that the gender-referred boys and control girls preferred lighter shades, whereas the gender-referred girls and control boys preferred darker shades. Qualitative analysis indicated that gender-specific justifications were uncommon, even for the sex-dimorphic colors. Gender-referred children showed inverted gender-stereotyped color preferences, which are likely related to their more general pattern of cross-gender identification. Principles of gender-differentiated development derived from gender-schema theory are used to explain the group differences in color preferences.     

An analysis of hope as a psychological strength

Psychologists have placed an increased emphasis on identifying psychological strengths that foster healthy development. Hope, as operationalized in Snyder's hope theory Snyder, C. R., Hoza, B., Pelham, W. E., Rapoff, M., Ware, L., & Danovsky, M., et al. (1997). The development and validation of the children’s hope scale. Journal of Pediatric Psychology, 22, 399-421], is one such cognitive-motivational construct that has received recent attention as a potential psychological strength that may serve as a protective factor for adolescents in the face of adverse life events. This longitudinal study, involving middle and high school students, provided evidence of (1) stability of hope reports of adolescents over a 1-year period, (2) predictive validity of adolescent hope reports, and (3) hope's functional role as a moderator in the relationship between stressful life events and adolescent well-being. Taken together, the results provide support for consideration of hope as a key psychological strength in youth. The findings are consistent with theories of motivation in which individual differences in hopeful thinking are conceptualized to play a functional role in linking life events and psychological well being.     

An Ecological View of School Satisfaction in Adolescence: Linkages Between Social Support and Behavior Problems

This study investigated the relationships among school satisfaction, social support, and problem behaviors in adolescents. Modest associations were found between school satisfaction and the demographic variables of gender, race, age, and grade level. Support from teachers, parents, and classmates contributed unique variance to ratings of school satisfaction; with teacher support contributing the most unique variance. School satisfaction mediated the relationship between social support and internalizing and externalizing behaviors. School satisfaction did not moderate the relationship between social support and problem behavior; however, it did serve as a protective factor across all levels of social support. Implications are discussed, including suggestions for developing interventions that focus on increasing support for adolescents in efforts to improve school satisfaction and reduce problem behaviors.     

Too cheap to chug: frugality as a buffer against college‐student drinking

• Beyond its probable effect on preventing financial problems, frugality may contribute to consumer well‐being in other ways. Using survey data collected from American undergraduates, in this paper we demonstrate that frugality is negatively associated with several types of alcohol use. These relationships hold even when sex and impulsivity are controlled. To further substantiate the link between frugality and college‐student drinking, we confirmed that typical amount spent on alcohol mediates the relations between frugality and each type of drinking we assessed. These results are consistent with suggestions that young adults' drinking‐related choices are subject to price considerations and that policy makers may be able to leverage such considerations to prevent excessive drinking.
