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.

The Unconscious Consumer: Effects of Environment on Consumer Behavior

In this article, we argue that consumer behavior is often strongly influenced by subtle environmental cues. Using grocery shopping as an example (or a “leitmotif,” if you wish), we first argue that the traditional perspective on consumer choice based on conscious information processing leaves much variance to be explained. Instead, we propose that many choices are made unconsciously and are strongly affected by the environment. Our argument is based on research on the perception–behavior link and on automatic goal pursuit.     

Accountability for others,perceived resources,and well being: Convergent restricted non‐linear results in two samples

This two‐sample investigation examined the influence of perceived resources on the form and magnitude of the relationships between accountability for others (AFO) and job tension and job satisfaction. Employing resource theory, we hypothesized that the non‐linear relationship between AFO and job tension would surface only for individuals high in perceived resources, whereas the association between these constructs would be positive and linear for individuals low in perceived resources. A similar relationship was hypothesized for AFO and job satisfaction in which the non‐linear effect would arise for individuals high in perceived resources, and negative linear effects would emerge for those low in perceived resources. Data from two samples (N= 201; N= 182) provided support and replication for the hypotheses. Implications of the results and directions for future research are discussed.     

Representations of Romantic Relationships, Romantic Experience and Sexual Behavior in Adolescence

Associations between romantic views and sexual behavior were examined in a community sample of 200 high school adolescents. This study incorporated interview and self‐report measures of romantic views, assessed multiple facets of sexual behavior (frequency, rapidity, onset, and risky behavior), and examined light nongenital, heavy nongenital, and genital sexual behaviors. Avoidant romantic views were related to later onset of genital sexual behavior and less frequent sexual behavior, particularly light and heavy nongenital behaviors. Anxious views were related to more frequent sexual behavior and more risky behavior. Direct effects were found between avoidant views and light and heavy nongenital sexual frequency, and indirect effects were found between avoidant views and genital frequency, onset of heavy nongenital and genital sexual behavior.     

Student or situation? Personality and classroom context as predictors of attitudes about business school cheating

Many business faculties may question why their students cheat. While past research shows that student characteristics predict cheating attitudes and behavior, evidence exists that attributes of classroom contexts also play a part. We investigate how three personality traits (conscientiousness, emotional stability, and openness to experience) and two context variables (classroom culture and pedagogy) affect business students’ attitudes toward cheating. Of the personality variables, only conscientiousness directly predicts cheating attitudes, while both context variables show significant relationships. Interactions indicate that conscientiousness, emotional stability, and openness to experience, in combination with context variables, affect some attitudes toward cheating. We recommend actions that might minimize cheating as well as future research directions.     

Response latency as an index of response strength during functional analyses of problem behavior

Dependent variables in research on problem behavior typically are based on measures of response repetition, but these measures may be problematic when behavior poses high risk or when its occurrence terminates a session. We examined response latency as the index of behavior during assessment. In Experiment 1, we compared response rate and latency to the first response under acquisition and maintenance conditions. In Experiment 2, we compared data from existing functional analyses when graphed as rate versus latency. In Experiment 3, we compared results from pairs of independent functional analyses. Sessions in the first analysis were terminated following the first occurrence of behavior, whereas sessions in the second analysis lasted for 10 min. Results of all three studies showed an inverse relation between rate and latency, indicating that latency might be a useful measure of responding when repeated occurrences of behavior are undesirable or impractical to arrange.     

Relationship of Ethnic Identity,Acculturation, and Psychological Well‐Being Among Chinese,Japanese, and Korean Americans

The current investigation examined the relationship of ethnic identity, acculturation, and psychological functioning among 334 Chinese, Japanese, and Korean American participants. Multiple regression analyses revealed that ethnic identity and acculturation differentially predicted well‐being on the basis of ethnic group membership. Results also indicated that a bicultural worldview was positively associated with psychological well‐being. Implications for counseling and recommendations for future research are discussed.
