Bell's theorem in an indeterministic universe

A variation of Bell's theorem that deals with the indeterministic case is formulated and proved within the logical framework of Lewis's theory of counterfactuals. The no-faster-than-light-influence condition is expressed in terms of Lewis would counterfactual conditionals. Objections to this procedure raised by certain philosophers of science are examined and answered. The theorem shows that the incompatibility between the predictions of quantum theory and the idea of no faster-than-light influence cannot be ascribed to any auxiliary or tacit assumption of either determinism or the related idea that outcomes of unperformed measurements are determinate within nature. In addition, the theorem provides an example of an application of Lewis's theory of counterfactuals in a rigorous scientific context.     

Family Profiles of Cohesion and Parenting Practices and Latino Youth Adjustment

Using a sample of 279 (52% female) Latino youth in 9th grade (M = 14.57, SD = .56), we examined profiles of family cohesion and parenting practices and their relation to youth adjustment. The results of latent profile analyses revealed four family profiles: Engaged, Supportive, Intrusive, and Disengaged. Latino youth in the Supportive family profile showed most positive adjustment (highest self‐esteem and lowest depressive symptoms), followed by youth in the Engaged family profile. Youth in the Intrusive and Disengaged profiles showed the lowest levels of positive adjustment. The findings contribute to the current literature on family dynamics, family profiles, and youth psychological adjustment within specific ethnic groups.     

Renewal during functional communication training

Functional communication training (FCT) is one of the most commonly prescribed interventions for the treatment of severe destructive behavior exhibited by individuals with intellectual disabilities. Although highly effective, FCT has been shown to fail in some cases when treatment is introduced into the child's typical environment. Basic and translational research on renewal provides a model for studying the relapse of destructive behavior following successful response to treatment in clinic settings using FCT. In the present study, we evaluated whether relapse of destructive behavior could be attributed to the discriminative control of the home context, which was historically correlated with reinforcement for destructive behavior. We implemented baseline contingencies in the home setting with caregivers acting as interventionists (i.e., Context A). We then implemented FCT in a treatment clinic with trained therapists (i.e., Context B). Finally, we introduced FCT in the home setting with caregivers implementing the treatment procedures (i.e., return to Context A). For three of four participants we observed the relapse of destructive behavior consistent with operant renewal. We discuss the implications of these findings with respect to strategies designed to promote generalization of FCT across settings during the treatment of severe destructive behavior.     

Supporting child witnesses during identification lineups: Exploring the effectiveness of registered intermediaries

Performance at identification lineup was assessed in eighty‐five 6‐ to 11‐year‐old typically developing children. Children viewed a live staged event involving 2 male actors, and were asked to identify the perpetrators from 2 separate lineups (one perpetrator‐present lineup and one perpetrator‐absent lineup). Half the children took part in lineups adapted by a registered intermediary (an impartial, trained professional who facilitates understanding and communication between vulnerable witnesses and members of the justice system), and half took part in “best‐practice” lineups, according to the current guidance for eyewitness identification in England and Wales. Children receiving assistance from a registered intermediary (relative to children who received best‐practice lineups) were more accurate in their identifications for perpetrator‐present lineups, and there was some evidence that they were also more accurate for perpetrator‐absent lineups. This provides the first empirical evidence for the effectiveness of registered intermediary support during identification lineups.

The human newborn’s umwelt: Unexplored pathways and perspectives

Historically, newborns, and especially premature newborns, were thought to “feel nothing.” However, over the past decades, a growing body of evidence has shown that newborns are aware of their environment, but the extent and the onset of some sensory capacities remain largely unknown. The goal of this review is to update our current knowledge concerning newborns’ perceptual world and how ready they are to cope with an entirely different sensory environment following birth. We aim to establish not only how and when each sensory ability arises during the pre-/postbirth period but also discuss how senses are studied. We conclude that although many studies converge to show that newborns are clearly sentient beings, much is still unknown. Further, we identify a series of internal and external factors that could explain discrepancies between studies, and we propose perspectives for future studies. Finally, through examples from animal studies, we illustrate the importance of this detailed knowledge to pursue the enhancement of newborns’ daily living conditions. Indeed, this is a prerequisite for assessing the effects of the physical environment and routine procedures on newborns’ welfare.     

Good and Bad Sides of Self-Compassion: A Face Validity Check of the Self-Compassion Scale and an Investigation of its Relations to Coping and Emotional Symptoms in Non-Clinical Adolescents

To demonstrate that the positive and negative subscales of Self-Compassion Scale (SCS) are very different in nature, we conducted a series of face validity checks on the items of this questionnaire among psychologists and psychology students (Study 1). Furthermore, a survey was administered to a convenience sample of non-clinical adolescents to examine the relations between various SCS subscales and symptoms of anxiety and depression as well as coping styles (Study 2). The results of the face validity checks revealed that the positive subscales seem to be well in line with the protective nature of self-compassion as they were mainly associated with cognitive coping and healthy functioning, whereas the negative subscales were chiefly associated with psychopathological symptoms and mental illness. The survey data demonstrated that the positive SCS subscales were positively correlated with adaptive coping (r’s between .22 and .50) and negatively correlated with symptoms of anxiety and depression (r’s between ?.19 and ?.53), while the negative subscales were positively correlated with symptoms (r’s between .49 and .61) and maladaptive coping strategies such as passive reacting (r’s between .53 and .56). Additional analyses indicated the negative subscales of the SCS accounted for a significant proportion of the variance in symptoms, whereas the unique contribution of the positive SCS subscales was fairly marginal. We caution to employ the total SCS score that includes the reversed negative subscales as such a procedure clearly inflates the relation between self-compassion and psychopathology.
