Racial Perceptions and Evaluative Responses to Welfare: Does Education Attenuate Race‐of‐Target Effects?

A growing body of research indicates that welfare attitudes may be strongly shaped by negative perceptions of Blacks. This raises questions about what might inhibit the racialization of welfare attitudes. In this vein, a long line of work indicating that education leads to increased tolerance suggests that the relationship between negative racial perceptions and welfare attitudes may be weaker among the highly educated. However, recent studies suggest that the role of education may be more complex: While negative racial perceptions may be less prevalent among the highly educated, the relationship between these perceptions and policy attitudes appears to be stronger among highly educated individuals. The present study attempts to extend this finding by examining the hypothesis that the presence of a racial cue would be more (rather than less) likely to strengthen the relationship between negative racial perceptions and evaluative responses to welfare among college-educated Whites. Data from a survey-based experiment included in the 1991 National Race and Politics Study provided a clear pattern of support for this hypothesis.     

Attention control and susceptibility to hypnosis

The present work aimed at assessing whether the interference exerted by task-irrelevant spatial information is comparable in high- and low-susceptible individuals and whether it may be eliminated by means of a specific posthypnotic suggestion. To this purpose high- and low-susceptible participants were tested using a Simon-like interference task after the administration of a suggestion aimed at preventing the processing of the irrelevant spatial information conveyed by the stimuli. The suggestion could be administered either in the absence or following a standard hypnotic induction. We showed that, outside from the hypnotic context, the Simon effect was similar in high and low-susceptible participants and it was significantly reduced following the posthypnotic suggestion in high-susceptible participants only. These results show that a specific posthypnotic suggestion can alter information processing in high-susceptible individuals and reduce the interfering effect exerted by arrow stimuli.     

PIGEONS (COLUMBA LIVIA) APPROACH NASH EQUILIBRIUM IN EXPERIMENTAL MATCHING PENNIES COMPETITIONS

The game of Matching Pennies (MP), a simplified version of the more popular Rock, Papers, Scissors, schematically represents competitions between organisms with incentives to predict each other's behavior. Optimal performance in iterated MP competitions involves the production of random choice patterns and the detection of nonrandomness in the opponent's choices. The purpose of this study was to replicate systematic deviations from optimal choice observed in humans when playing MP, and to establish whether suboptimal performance was better described by a modified linear learning model or by a more cognitively sophisticated reinforcement‐tracking model. Two pairs of pigeons played iterated MP competitions; payoffs for successful choices (e.g., “Rock” vs. “Scissors”) varied within experimental sessions and across experimental conditions, and were signaled by visual stimuli. Pigeons' behavior adjusted to payoff matrices; divergences from optimal play were analogous to those usually demonstrated by humans, except for the tendency of pigeons to persist on prior choices. Suboptimal play was well characterized by a linear learning model of the kind widely used to describe human performance. This linear learning model may thus serve as default account of competitive performance against which the imputation of cognitively sophisticated processes can be evaluated.     

The consolidation of object and context recognition memory involve different regions of the temporal lobe

These experiments investigated the involvement of several temporal lobe regions in consolidation of recognition memory. Anisomycin, a protein synthesis inhibitor, was infused into the hippocampus, perirhinal cortex, insular cortex, or basolateral amygdala of rats immediately after the sample phase of object or object-in-context recognition memory training. Anisomycin infused into perirhinal or insular cortices blocked long-term (24 h), but not short-term (90 min) object recognition memory. Infusions into the hippocampus or amygdala did not impair object recognition memory. Anisomycin infused into the hippocampus blocked long-term, but not short-term object-in-context recognition memory, whereas infusions administered into the perirhinal cortex, insular cortex, or amygdala did not affect object-in-context recognition memory. These results clearly indicate that distinct regions of the temporal lobe are differentially involved in long-term object and object-in-context recognition memory. Whereas perirhinal and insular cortices are required for consolidation of familiar objects, the hippocampus is necessary for consolidation of contextual information of recognition memory. Altogether, these results suggest that temporal lobe structures are differentially involved in recognition memory consolidation.     

Using Liberation Psychology and Dialectical Humanism to Understand Latinx Adolescents’ Life Satisfaction and Depressive Symptoms

The authors conducted a study to examine how the presence of meaning in life, search for meaning in life, hope, family importance, and enculturation influenced Latinx adolescent students’ depressive symptoms and life satisfaction. Two regression models revealed there was a statistically significant relationship between predictor variables, life satisfaction, and depression. The article concludes with a discussion regarding the importance of these findings and recommendations for practice and research. Los autores llevaron a cabo un estudio para examinar cómo la presencia de sentido en la vida, la búsqueda de sentido en la vida, la esperanza, la importancia de la familia y la enculturación influyeron en los síntomas depresivos y satisfacción vital de estudiantes adolescentes Latinx. Dos modelos de regresión revelaron que existe una relación estadísticamente significativa entre las variables de predicción, la satisfacción vital y la depresión. Este artículo concluye con una discusión en torno a la importancia de estos hallazgos, así como recomendaciones para la práctica y la investigación.     

Small-sample characterization of stochastic approximation staircases in forced-choice adaptive threshold estimation

Despite the widespread use of up-down staircases in adaptive threshold estimation, their efficiency and usability in forced-choice experiments has been recently debated. In this study, simulation techniques were used to determine the small-sample convergence properties of stochastic approximation (SA) staircases as a function of several experimental parameters. We found that satisfying some general requirements (use of the accelerated SA algorithm, clear suprathreshold initial stimulus intensity, large initial step size) the convergence was accurate independently of the spread of the underlying psychometric function. SA staircases were also reliable for targeting percent-correct levels far from the midpoint of the psychometric function and performed better than classical up-down staircases with fixed step size. These results prompt the utilization of SA staircases in practical forced-choice estimation of sensory thresholds.     

Predicting attitude extremity: the interactive effects of schema development and the need to evaluate and their mediation by evaluative integration

Research on attitude extremity suggests that schemas containing more information about a particular attitude domain are more likely to be associated with extreme attitudes toward objects in that domain when perceivers' responses toward features of the domain are evaluatively integrated. The present study argues that a high need to evaluate may play an important role in determining when schema development will be associated with the integrated responses to different domain features necessary for extremity. Consistent with this argument, data from a nationally representative survey of political attitudes indicated that the need to evaluate was associated with increased extremity across two different indices of the latter; that it moderated the relationships between schema development (in the form of political expertise), on one hand, and increased extremity and integration, on the other; and that the moderating effects of the need to evaluate vis-a-vis extremity were mediated by integration.     

A Developmental Perspective of Marriage and Family Therapist's Ethical Principles: Support for the Practitioner–Ethics Relationship Model

This study explored therapists' professional ethics by assessing therapist at-risk behaviors as they relate to ethical proficiency in the field of Marriage and Family Therapy. A survey assessing practice behaviors was distributed among marriage and family therapists (MFTs) of varying levels of experience. Data gathered were analyzed using factor analysis, structural equation modeling, and multiple regression. Results indicate a positive relationship between the latent variables of risk and justification, as well as a significant relationship between these variables and years of clinical experience. Findings provide evidence to support the practitioner–ethics relationship model proposed by the authors. Implications of these findings, as well as future directions for research and policy are suggested.     

On the ethics of facial transplantation research

Transplantation continues to push the frontiers of medicine into domains that summon forth troublesome ethical questions. Looming on the frontier today is human facial transplantation. We develop criteria that, we maintain, must be satisfied in order to ethically undertake this as-yet-untried transplant procedure. We draw on the criteria advanced by Dr. Francis Moore in the late 1980s for introducing innovative procedures in transplant surgery. In addition to these we also insist that human face transplantation must meet all the ethical requirements usually applied to health care research. We summarize the achievements of transplant surgery to date, focusing in particular on the safety and efficacy of immunosuppressive medications. We also emphasize the importance of risk/benefit assessments that take into account the physical, aesthetic, psychological, and social dimensions of facial disfiguration, reconstruction, and transplantation. Finally, we maintain that the time has come to move facial transplantation research into the clinical phase.     

Ethical Issues and At-Risk Behaviors in Marriage and Family Therapy: A Qualitative Study of Awareness

This exploratory study investigated perceptions of and relationship with professional ethics of therapists-in-training. A focus group of marriage and family therapy doctoral students explored self-awareness and at-risk behaviors regarding ethical competence and compliance. A grounded theory analysis of data is presented as a conditional matrix, which offers a theory of development between therapists and their perception of ethics. The Practitioner-Relationship Ethics Model represents findings of interaction between confidence in ethical principles, field experience, use of justification, and at-risk behaviors. Implications and limitations of these findings are presented, as are suggestions for research.
