Use of kind information for object individuation in young domestic chicks

In this paper, we studied the ability of newborn chicks to use kind information (sortal objects) provided by social and food attractors to determine the number of distinct objects present in an event (object individuation). Newly hatched chicks were reared with five imprinting objects and were fed mealworms. Chicks’ spontaneous tendency to approach the larger group of items was exploited. At test, on day 2 post-hatching, chicks observed two events in which objects, differing in kind, were each hidden behind one of two identical screens. Approaching either screen was considered a preferential choice. In Experiment 1, chicks presented with two social versus two food attractors did not exhibit any preference. In contrast, in Experiment 2, when chicks saw two different attractors (one social and one food) hidden behind a screen and one attractor hidden twice (i.e. moved back and forth two times) behind the other screen, they spontaneously approached the two different attractors rather than the single one seen twice. An explanation based on the preference for the more varied set was ruled out in Experiment 3: chicks did not preferentially choose between two different versus two identical objects when both groups were simultaneously presented. Results suggest for the first time that a non-human species uses kind information for individuating objects in a cross-basic-level contrast (i.e. food and social items) with minimal experience. As social and food stimuli differ in property as well as in kind information, the alternative explanation accounting for use of property information alone is also discussed.     

The moderating role of pessimism in the association between retrospective relational peer victimization,interpersonal risk factors,and suicide ideation

Peer victimization (PV) is a serious concern for youth and is associated with subsequent suicide ideation in young adulthood. The interpersonal theory of suicide may provide a framework for understanding suicide ideation in this population. Specifically, thwarted belongingness (TB) and perceived burdensomeness (PB) have been significantly associated with suicide ideation among young adults with a history of peer victimization. Additionally, the personality trait of pessimism is associated with elevated suicide ideation. Thus, this study tested the association between self-reported frequency of retrospective relational (i.e., verbal and indirect) PV in primary and secondary school, thwarted interpersonal needs (TB and PB), and current suicide ideation, as well as how these relations may vary based on current pessimism. Participants were 330 undergraduate students. Nonparametric bootstrap moderated mediation procedures were used to test hypotheses. Results indicated significant indirect effects of frequency of retrospective relational PV and suicide ideation through PB and TB. Contrary to predictions, results did not indicate significant moderated mediation; however, the association between PB and suicide ideation was stronger at lower pessimism levels. We also provide supplemental analysis with optimism as the moderator. These findings suggest that clinicians may consider targeting TB, PB, as well as pessimism and optimism among those with a history of relational PV when assessing and intervening on current suicide ideation. Implications, limitations, and future directions are further discussed.     

Is Committed Desire Intentional? A Qualitative Exploration of Sexual Desire and Differentiation of Self in Couples

The question of what heightens or diminishes sexual desire has long been a passionate theme across cultures in literature, arts, media, and medicine. Yet, little research has been conducted to determine what affects level of desire within couples. The degree of differentiation of self has been suggested as an important variable in shaping partners' level of desire. Through a qualitative analysis of dyadic couple interviews, this study provides an account of characteristics, processes, and trajectories of sexual desire and differentiation in 33 heterosexual couples of varying ages and relationship duration. Factors associated with high desire were change and autonomy, whereas conflict and children were reported to be desire‐diminishing factors. Innovation, sharing, autonomy, and effort emerged as desire‐promoting strategies, while fostering personal interests, investing in a positive connection, and enhancing personal integrity were identified as couples' strategies to promote and preserve differentiation of self. The results also shed light on couples' perceptions of whether and how sexual desire changes over the course of the relationship and challenge common cultural assumptions about desire in committed relationships—namely the myth that the only authentic expression of desire is that which occurs spontaneously and without intention and planning. Implications for couple therapy are discussed.     

Adaptive preferences: merging political accounts and well-being accounts

Accounts of adaptive preferences are of two kinds: well-being accounts fully theorized for their own sake and political accounts theorized to facilitate the political project of reducing oppression and marginalization. Given their practical role, the latter are often less fully theorized, and are therefore less robust to theoretical criticism. In this paper, I first draw on well-being accounts to identify the well-theorized elements that political accounts should want to adopt in order to strengthen their project and avoid common criticisms. Second, I appeal to the political project to show the shortcomings of the well-being accounts on which I draw.     

The Effects of Using a Conditioned Stimulus to Cue DRO Schedules

A reversal design was used to examine the effects of a differential reinforcement of other behavior (DRO) procedure and the presence of a stimulus (i.e., a bracelet), conditioned via discrimination training, on reducing socially maintained non‐contextual vocalizations in an adolescent girl with autism. Initially, a functional analysis determined that non‐contextual vocalizations were maintained by social attention. Then, discrimination training was used to establish the presence of the bracelet as a discriminative stimulus for the absence of vocalizations. Specifically, when the bracelet was on, non‐contextual vocalizations were interrupted, and edible reinforcement was provided for the absence of vocalizations. When the bracelet was off, vocalizations were not interrupted and the teacher provided social attention to the participant (i.e., reciprocated conversation with the participant about the topic). During intervention, a DRO procedure was used. The participant was presented with the bracelet, a timer set for a specified interval, and the instruction to work quietly. If vocalizations did not occur for the entire duration of the interval, the bracelet was removed and the learner was given the opportunity to engage in vocalizations. The DRO interval was systematically increased throughout the intervention. Results are discussed in terms of discrimination training as an effective addition to differential reinforcement procedure.

Exploring perspectives of well-being in Latina/o migrant workers

Migrant workers enter the United States to meet the agricultural labor needs of the US, seeking a better life and an escape from poverty. However, little is known about the factors that influence well-being in this population as they transition to a new society. The purpose of this study was to describe Latina/o migrant workers’ perceptions regarding the individual, communal, and contextual factors that influence their well-being. A community-based qualitative approach was taken to describe perceptions of well-being in the Latina/o migrant worker population. Focus groups and individual interviews were conducted with 12 South Florida Latina/o migrant workers using a semi-structured interview guided by the Developmental Systems Theory and Prilleltensky’s conceptualization of well-being. Conventional content analysis identified five themes: children as a point of connection, a mosaic of informal support, navigating a multi-stressed life context, awareness of lack of agency, and toward the promotion of well-being. This study is one of the first explorations of well-being in Latina/o migrant workers and includes recommendations for providers, researchers, and advocates.     

Suicide attempts and stressful life events among homeless people in Madrid (Spain)

The article describes a study carried out with a representative sample of homeless people in Madrid (Spain; N = 188). This study aims to corroborate the relationship identified in the literature between stressful life events and suicidal behaviour in a group in a situation of social exclusion, to assess the differences in the number and characteristics of stressful life events experienced by homeless people who are attempters and non‐attempters, and to identify which combination of stressful life events enables discrimination for suicide attempts among homeless people. The results show that 30% of homeless people in Madrid had attempted suicide, and 57.9% of them had done so for the first time when they were homeless. The interviewees are shown to have experienced a large amount of stressful life events, with substantially more stressors experienced by the homeless people who tried to commit suicide, during both their childhood and adolescence and throughout their life. Finally, we found that the combination of 7 stressful life events provided the best possible discrimination between homeless attempters and non‐attempters.     

Subjective Wellbeing Between Organizational Bonds and Cultural Contaminations

Positive Psychology has recently attempted at “enlarging the paradigm,” explaining the understanding of the human experience of the world. By contrast, for Critical Psychology, “enlarging the paradigm” means moving away from an individualist conceptualization of the psychological. The present article aims at “redistributing the Psychological” toward directions already marked by cultural and discursive conceptions of human experience. Within a transdisciplinary frame, labeled as Psycho-semiotics, Diatextual Analysis has been adopted to investigate the rhetorical modes used by socially excluded enunciators (drug users, immigrants, atypical workers, elderly people, and some categories of churchgoer) to elaborate their own experience of well-being through affective labor and self care.
