Baseline reinforcement rate and resurgence of destructive behavior

Concepts from behavioral momentum theory, along with some empirical findings, suggest that the rate of baseline reinforcement may contribute to the relapse of severe destructive behavior. With seven children who engaged in destructive behavior, we tested this hypothesis in the context of functional communication training by comparing the effects of different baseline reinforcement rates on resurgence during a treatment challenge (i.e., extinction). We observed convincing resurgence of destructive behavior in four of seven participants, and we observed more resurgence in the condition associated with high‐rate baseline reinforcement (i.e., variable‐interval 2 s in Experiment 1 or fixed‐ratio 1 in Experiment 2) compared to a low‐rate baseline reinforcement condition. We discuss the implications of these results relative to schedules of reinforcement in the treatment of destructive behavior and strategies to mitigate resurgence in clinical settings.

Does Cooperation in the Laboratory Reflect the Operation of a Broad Trait?

The Dictator Game, a face valid measure of altruism, and the Trust Game, a face valid measure of trust and trustworthiness, are among the most widely used behavioural measures in human cooperation research. Researchers have observed considerable covariation among these and other economic games, leading them to assert that there exists a general human propensity to cooperate that varies in strength across individuals and manifests itself across a variety of social settings. To formalize this hypothesis, we created an S‐1 bifactor model using 276 participants' Dictator Game and Trust Game decisions. The general factor had significant, moderate associations with self‐reported and peer‐reported altruism, trust, and trustworthiness. Thus, the positive covariation among economic games is not reducible to the games' shared situational features. Two hundred participants returned for a second session. The general factor based on Dictator Game and Trust Game decisions from this session did not significantly predict self‐reported and peer‐reported cooperation, suggesting that experience with economic games causes them to measure different traits from those that are reflected in self‐assessments and peer‐assessments of cooperativeness. © 2018 European Association of Personality Psychology     

The WISC-V in children and adolescents with epilepsy

Despite its popularity in the neuropsychological evaluation of children, the utility of the Wechsler Intelligence Scale for Children – Fifth Edition (WISC-V) has not yet been investigated in children with epilepsy. Eighty clinically referred children and adolescents with epilepsy were administered the WISC-V as part of a comprehensive assessment and scores were compared to matched controls from the WISC-V standardization sample. T tests compared WISC-V indices and subtests between patients and controls and Chi-square analyses compared the rates of low scores. Correlational analyses assessed the relationships between epilepsy severity variables (e.g., age of onset, duration of epilepsy, number of antiepileptic drugs, seizure frequency). All WISC-V composites and subtests were significantly lower in patients versus controls and the rate of low scores was higher in patients than controls for all composites and subtests with the exception of Figure Weights. The Working Memory Index and Processing Speed Index were most sensitive to impairment, while the Verbal Comprehension Index and Fluid Reasoning Index were least sensitive. Of the epilepsy severity variables, age of seizure onset and number of antiepileptic drugs were strong predictors of deficits, whereas seizure frequency was the weakest predictor. Importantly, no significant differences were seen in children with right hemisphere epilepsy versus left on the five WISC-V composites, though a trend was seen towards a lower Visual-Spatial Index in those with right-sided focal seizures.     

Toward a comprehensive model of face impressions: What we know,what we do not,and paths forward

A person's impression of another depends upon three sources of variance. The characteristics of the target, the characteristics of the perceiver, and the interplay between the two. Researchers have dedicated different amounts of study to these three sources of variance, and therefore they differ in how well they are understood. The present work will first review the portions of the face impression process that are understood well, then identify and discuss portions of the process less well understood. We will then question to what extent the current state of knowledge will generalize to novel targets and populations. Finally, we will review several modeling approaches that can accommodate relatively unexamined yet important sources of variance in impression formation, suggesting a clear path forward toward a comprehensive understanding of face impressions.     

The Perceptual Basis of Vast Space

“Vast” is a word often applied to environmental terrain that is perceived to have large spatial extent. This judgment is made even at viewing distances where traditional metric depth cues are not useful. This paper explores the perceptual basis of vast experience, including reliability and visual precursors. Experiment 1 demonstrated strong agreement in ratings of the spatial extent of two-dimensional (2D) scene images by participants in two countries under very different viewing conditions. Image categories labeled “vast” often exemplified scene attributes of ruggedness and openness (Oliva & Torralba, 2001). Experiment 2 quantitatively assessed whether these properties predict vastness. High vastness ratings were associated with highly open, or moderately open but rugged, scenes. Experiment 3 provided evidence, consistent with theory, that metric distance perception does not directly mediate the observed vastness ratings. The question remains as to how people perceive vast space when information about environmental scale is unavailable from metric depth cues or associated scene properties. We consider possible answers, including contribution from strong cues to relative depth.     

Examining the Unique Characteristics of a Non-Probability Sample of Undocumented Female Sex Workers with Dependent Children: The Case of Haitians in the Dominican Republic

Haitians in the Dominican Republic (DR) are increasingly marginalized due to recent legislation that stripped Haitian-Dominicans of their citizenship and increased Haitian migrants’ deportation risk. Haitian female sex workers (FSWs) are particularly vulnerable, though little is known about them. This study will help public health efforts targeted at sex workers to better reach Haitian FSWs and address their needs by identifying a profile of characteristics unique to this group compared to Dominican FSWs. Data were collected in 2014 among Haitian and Dominican FSWs in Puerto Plata, DR. Surveys assessed respondents’ demographics, health consciousness, depression, and stigma. Adjusted logistic regressions showed that Haitian FSWs were disadvantaged: they had significantly lower rates of education, more children, and less permanent income. Furthermore, Haitian FSWs were more likely to work independently and for fewer hours. Interestingly, Haitian FSWs internalized less stigma than Dominicans. Though we can only speculate, this could be due to migration for sex work, or the lack of formal employment for Haitians. Initiatives to alleviate poverty, create formal jobs, and overturn discriminatory legislation may have the most impact for Haitian FSWs.     

Challenging Doris’ Attack on Aggregation: Why We are Not Left “Completely in the Dark” about Global Virtues

Aggregation (the process of collecting multiple observations of behavior and averaging them before predicting behavior) shows that virtue-relevant behavior is indeed highly predictable, and that individual differences in global virtues do indeed exist. Aggregation is a key response to the situationist argument against the existence of broad virtues. However, a concern with aggregation is that, because it is an average, the specifics of what are included in that average matter. In particular, if heinous actions could be included in the average, then aggregates cannot provide enough confidence that the holders of high aggregates (e.g., highly compassionate people) have not conducted heinous actions and thus cannot provide enough confidence that such people qualify as virtuous. Doris (2002) has challenged aggregation with this concern, and no one has responded substantively to this challenge. If Doris’ challenge is in fact correct, then the situationist argument against the existence of broad virtues stands. In the article, we present a full response to this concern. We argue that aggregation does not in fact allow heinous exceptions, because aggregates do indeed predict extreme single behaviors very well. In fact, aggregates do allow confidence that holders of high aggregates do not commit heinous actions. Thus, Doris’ rejection of the aggregation solution does not defeat aggregation, aggregation continues to stand in the defense of global virtues, and the situationist argument does not threaten the existence and predictive power of global virtues. Models of traits that rely on aggregates, such as Whole Trait Theory (Fleeson and Jayawickreme 2015), may provide useful post-situationist models of virtues.
