The effect of type of behavior on behavior change caused by type of upcoming food substance

Previous research suggests that rats will decrease their consumption of a low-valued substance if a high-valued one will soon be available (anticipatory contrast), but will increase their rate of operant responding for a low-valued substance if a high-valued one will soon be available (positive induction). The present experiments tested whether rats would increase their operant rate of licking or lever pressing for 1% liquid-sucrose reinforcement when 32% sucrose reinforcement was upcoming in the same session. Results indicated that upcoming 32% sucrose increased rates of lever pressing for 1% sucrose, but did not produce similar increases in rates of licking. In fact, upcoming 32% sucrose significantly reduced lick rates in Experiment 2. The present results suggest that the different changes in behavior may be linked to the specific response that the subjects must engage in to obtain the reward (i.e., licking vs. lever pressing), and not to the function of the behavior (i.e., consummatory vs. operant) or to how frequently the substances are available (i.e., continuously vs. intermittently).     

Staff survey results and characteristics that predict assault and injury to personnel working in mental health facilities

The purpose of this study was to complete a mental health staff opinion survey to identify patient and staff characteristics associated with staff assault and injury in psychiatric treatment settings and to develop a model of prediction for staff assault and injury utilizing these survey variables. The data consisted of opinion surveys sent to staff of 15 child, adolescent, and adult psychiatry inpatient units in the United States. Multivariate logistic regression was used to determine the level of assault and staff‐reported injury prediction that could be obtained from the staff‐completed opinion survey. Responses indicated a high prevalence of reported aggression, with 62.3% of staff endorsing verbal and physical aggression, property destruction, and self‐injurious behavior as being prevalent at their site, whereas only 4.1% rated none of these as prevalent. Staff working with children and adolescents in settings with high rates of psychiatric diagnoses reported increased frequency of assault and injury compared with those working with adults. Younger, less experienced staff reported higher rates of assault and injury. Staff working with female patients reported similar rates of assault and injury to those working with males. A logistic regression analysis using staff‐reported survey results of both staff and patient characteristics predicted assault correctly 73.7% of the time and injury 66.1% of the time. Resources for violence prevention and staff training programs in violence prevention are needed in child and adolescent psychiatry wards. Results are consistent with theories emphasizing the importance of negative emotions and affects, impulsivity, and frustration in goal‐directed activities in human aggression. Aggr.

Agency and Virtue: Dimensions Underlying Subgroups of Women

Previous research indicates that the stereotype of women can be considered to have 3 subgroups: housewife, career woman, and sex object. In 2 samples (N = 19 and 35), we found evidence that these subgroups can be reliably distinguished in terms of 2 dimensions: agency and virtue. Participants sorted 27 feminine traits and then rated these traits in terms of their agency and virtue. Cluster analysis and multidimensional scaling with property fitting were used to identify subgroups, to fit virtue and agency dimensions to the subgroups, and to test for differences among the subgroups in terms of virtue and agency. Across both samples, agency and virtue fit the subgroups well (average R ² = .75), produced many significant differences among the subgroups, and are consistent with a system-justification perspective of sexism (Glick & Fiske, 2001) in which a belief in women's virtue and lack of agency reflects and maintains status differences between men and women.     

Adolescents’ Endorsement of Communal and Agentic Conflict-Management Strategies with Friends and Romantic Partners

To investigate contextual influences on gender differences and similarities, we compared adolescents’ endorsement of gender-typed communal/other-focused and agentic/self-focused conflict-management strategies in three relationship contexts: same-gender friends, other-gender friends, and other-gender heterosexual romantic partners. Our 2 Participant Gender (between-subjects) × 3 Relationship Context (within-subjects) mixed factorial design addressed whether findings of prior research (Keener and Strough 2017) with college-aged participants would generalize to adolescents. Participants (n?=?103; 47 male adolescents; 56 female adolescents, 14–17 years-old) from the U.S. South Atlantic and Middle Atlantic regions read nine hypothetical conflict scenarios (three per each relationship context) and rated their likelihood of using gender-typed strategies. Young women and men endorsed communal and agentic strategies significantly more in same- and other-gender friendships than in romantic relationships. Across all three relationship contexts, young women reported using significantly more agentic strategies than young men did. In contrast to previous research on college students (Keener and Strough 2017), the predicted Participant Gender x Relationship Context interaction was not significant in the present study. Our findings suggest that developmental processes such as age differences in gender socialization and lack of experience with romantic relationships might explain why findings from college students did not generalize to adolescents.

     

Putting on Virtue Without Putting Off Feminists

Mary Wollstonecraft's account of virtue discourse and formation, which deploys ancient and medieval ethical resources for modern purposes, challenges a prevalent narrative in Christian ethics today. Several prominent Christian virtue ethicists have left the false impression that serious reflection on the virtues depends on pre‐modern traditions and the eschewal of modern resources. Troubled by skeptical quandaries and the difficulty of adjudicating conflicting claims about virtue, they are concerned with securing a pre‐modern court of appeals. Many feminists worry that these appeals unduly constrain because they naturalize what is contingent and fix what should be open to debate. Wollstonecraft does not share the skeptical concerns and so has no need for metaethical appeals. Adapting Edmund Burke's moral philosophy, her use of virtue discourse deploys his metaphor of “the wardrobe of the moral imagination” to more religious, radical, and democratic ends. This way of proceeding signals the possibility of a rapprochement between feminists of various stripes and those interested in deploying the discourse of the virtues for contemporary Christian ethics.     

Distinguishing Between Subgroups of Adolescents Who Self‐Harm

The differences in factors associated with subgroups of adolescents in the continuum of deliberate self‐harm (DSH) phenomena were investigated. In an anonymous self‐report survey of 6,020 adolescents aged 15 and 16 years, 3.2% of adolescents (5.3% females, 1.3% males) reported DSH with intent to die, 2.8% (4.3% females; 1.5% males) reported DSH without intent to die, and 15% (22.4% females; 8.5% males) reported thoughts of DSH without acts. Regression analysis indicated considerable overlap in vulnerability factors along the spectrum of DSH thoughts and acts. A uniquely distinct relationship was found between DSH of a friend and DSH without intent to die on one hand and DSH of a family member with DSH with intent to die on the other. Results indicate that familial and nonfamilial social influences on DSH behavior may be important in designing prevention programs and that educational programs for the promotion of psychological well‐being may be helpful for adolescents at any point along the spectrum of DSH that was examined.     

The impact of novel labels on visual processing during infancy

The impact of novel labels on visual processing was investigated across two experiments with infants aged between 9 and 21 months. Infants viewed pairs of images across a series of preferential looking trials. On each trial, one image was novel, and the other image had previously been viewed by the infant. Some infants viewed images in silence; other infants viewed images accompanied by novel labels. The pattern of fixations both across and within trials revealed that infants in the labelling condition took longer to develop a novelty preference than infants in the silent condition. Our findings contrast with prior research by Robinson and Sloutsky (e.g., Robinson & Sloutsky, 2007a ; Sloutsky & Robinson, 2008 ) who found that novel labels did not disrupt visual processing for infants aged over a year. Provided that overall task demands are sufficiently high, it appears that labels can disrupt visual processing for infants during the developmental period of establishing a lexicon. The results suggest that when infants are processing labels and objects, attentional resources are shared across modalities.     

Candidate Vulnerability and Exposure to Counterattitudinal Information: Evidence From Two U.S. Presidential Elections

Politically motivated selective exposure has traditionally been understood through the lens of long‐standing attitudes and beliefs, but the role of environment in shaping information exposure practices merits further consideration. Citizens might respond to the political environment in their information‐seeking behavior for numerous reasons. Citizens who believe their position is politically vulnerable have specific cognitive and affective needs that may make them uniquely attuned to counterattitudinal information. In the context of a presidential election, this means that as the defeat of a supported candidate appears more likely, attention to counterattitudinal content will increase. Data collected in the 2008 and 2012 U.S. Presidential elections support this prediction, although this relationship was observed primarily among supporters of the Republican candidate in both elections.
