Personality Traits Predict Smartphone Usage

The present study investigates to what degree individual differences can predict frequency and duration of actual behaviour, manifested in mobile application (app) usage on smartphones. In particular, this work focuses on the identification of stable associations between personality on the factor and facet level, fluid intelligence, demography and app usage in 16 distinct categories. A total of 137 subjects (87 women and 50 men), with an average age of 24 (SD = 4.72), participated in a 90‐min psychometric lab session as well as in a subsequent 60‐day data logging study in the field. Our data suggest that personality traits predict mobile application usage in several specific categories such as communication, photography, gaming, transportation and entertainment. Extraversion, conscientiousness and agreeableness are better predictors of mobile application usage than basic demographic variables in several distinct categories. Furthermore, predictive performance is slightly higher for single factor—in comparison with facet‐level personality scores. Fluid intelligence and demographics additionally show stable associations with categorical app usage. In sum, this study demonstrates how individual differences can be effectively related to actual behaviour and how this can assist in understanding the behavioural underpinnings of personality.

The (In)visibility of Psychodiagnosticians' Expertise

This study investigates decision making in mental health care. Specifically, it compares the diagnostic decision outcomes (i.e., the quality of diagnoses) and the diagnostic decision process (i.e., pre‐decisional information acquisition patterns) of novice and experienced clinical psychologists. Participants' eye movements were recorded while they completed diagnostic tasks, classifying mental disorders. In line with previous research, our findings indicate that diagnosticians' performance is not related to their clinical experience. Eye‐tracking data provide corroborative evidence for this result from the process perspective: experience does not predict changes in cue inspection patterns. For future research into expertise in this domain, it is advisable to track individual differences between clinicians rather than study differences on the group level.

Aims and Exclusivity

If belief has an aim by being a (quasi) intentional activity, then it ought to be the case that the aim of belief can be weighed against other aims one might have. However, this is not so with the putative truth aim of belief: from the first‐person perspective, one can only be motivated by truth considerations in deliberation over what to believe (exclusivity). From this perspective then, the aim cannot be weighed. This problem is captured by David Owens's Exclusivity Objection to belief having an aim (2003). Conor McHugh (2012; 2013) has responded to this problem by denying the phenomenon of exclusivity and replacing it with something weaker: demandingness. If deliberation over what to believe is characterised by demandingness and not exclusivity, this allows for the requisite weighing of the truth aim. I argue against such a move by suggesting that where non‐evidential considerations play a role in affecting what we believe, these considerations merely change the standards required for believing in a particular context, they do not provide non‐evidential reasons for forming or withholding belief, which are considered as such from the deliberative perspective. Exclusivity thus remains, and so too does Owens's objection.     

Determining the Effectiveness of an Alcohol Intervention Program With Greek College Students

The authors examined the perception of college students from Greek organizations on the effectiveness of an alcohol intervention program that included gender‐specific programming. Significant reductions in risky alcohol use were found in men who attended and evaluated the program as helpful.     

Interculturality and Early Attachment: A Comparison of Urban/ <Emphasis Type="Italic">Non-Mapuche</Emphasis> and Rural/<Emphasis Type="Italic">Mapuche</Emphasis> Mother-Baby Dyads in Chile

It is well known in the field that culture and context play an important role in child rearing and parenting practices. However, many studies do not address the cultural dimension of attachment, although evidence indicates that aspects of early attachment differ across cultures. With the goal of comparing the quality of mother–baby interactions, this study analyzed attachment behaviors and maternal sensitivity in two settings: urban/non-Mapuche and rural/Mapuche in Chile. The sample was composed of 34 mother-baby dyads (17 urban/non-Mapuche and 17 rural/Mapuche) with 12-month-old children. During a feeding episode, the attachment style of the interaction was assessed with the Attachment during Stress scale, and maternal sensitivity was evaluated with the Child-Adult Relationship Experimental Index-Toddlers (CARE-Index). The groups differed in their interaction attachment style and in affective and proximity modalities: Urban/non-Mapuche mothers tended to have secure and ambivalent attachment styles, and rural/Mapuche mothers tended to have avoidant styles. When educational level is controlled, ethnicity group can explain the differences in mothers’ attachment styles. The findings of the study and their implications are discussed.     

Manipulations of vasopressin alter aggression differently across testing conditions in monogamous and non‐monogamous Peromyscus mice

Differences in the distribution of arginine vasopressin (AVP) and a subtype of AVP receptors, the V_1a receptor, may explain dissimilarities in social behavior of monogamous and non‐monogamous rodents. Intracerebroventricular infusions of AVP and a V_1a antagonist were used in sexually naive males of two mouse species, the monogamous and highly aggressive California mouse (Peromyscus californicus) and the non‐monogamous and less aggressive white‐footed mouse (P. leucopus), to begin testing the interaction between the social system of a species and the effects of AVP on aggression. Two testing conditions, the resident‐intruder aggression test (R‐I) and the neutral arena aggression test, were used because they may differ in function and underlying biological mechanisms. In the R‐I test, administration of the antagonist lengthened attack latencies in California mice. In contrast, blocking V_1a receptors did not alter attack latencies in the R‐I test in white‐footed mice or in the neutral arena aggression test in both species. AVP also did not alter aggression in either species in either behavioral test. Overall, these results suggest that AVP may be more likely to be associated with offensive aggression as measured in the R‐I test than with neutral arena aggression and that the effects of AVP manipulations may differ between monogamous and non‐monogamous rodents.

An exploratory analysis of the contexts and circumstances of filicide‐suicide in Chicago, 1965–1994

Filicide is the killing of a ward by a parent. Relative to many other types of homicide, filicide is an infrequent event. Filicide followed by the offender's suicide is less frequent still. The contexts and circumstances surrounding filicide‐suicide may nevertheless provide insight into parental psychology. Some research suggests, for example, that filicidal genetic parents are more likely to commit suicide than are filicidal stepparents. Five hypotheses are tested for this study, using a database that includes incident‐level information on over 22,000 homicides committed in Chicago during the years 1965–1994. Findings do not support the hypothesis of differential risk of suicide following filicide by genetic parents and stepparents. Previous work is replicated, indicating that: (1) filicides that include multiple victims are more likely to end in the offender's suicide than are filicides that include a single victim, (2) parents are more likely to commit suicide following a filicide of an older child than a filicide of a younger child, (3) older parents, relative to younger parents, are more likely to commit suicide following filicide, and that (4) fathers, relative to mothers, are more likely to commit suicide following filicide. Discussion suggests future directions for research that can inform our understanding of filicide and of filicide‐suicide. Aggr. Behav. 00:000–000, 2005. © 2005 Wiley‐Liss, Inc.
