Contrasting rule-based and similarity-based category learning: The effects of mood and prior knowledge on ambiguous categorization

This study adopts a dual-system view of category learning. The findings suggest that consumers who learn a dominant feature as a verbal rule for a product category will classify a new ambiguous product according to that feature even if it more closely resembles a different product category. The findings also demonstrate that dominant features can bias categorization toward a less prototypical category in the event that the new product breaks the rule. We refer to this phenomenon as criterial inferencing. Lastly, we offer unique empirical evidence to suggest that mood influences category learning and thus attenuates the criterial inferencing bias.     

Three-year follow-up of same-sex couples who had civil unions in Vermont, same-sex couples not in civil unions, and heterosexual married couples

This study was a 3-year follow-up of 65 male and 138 female same-sex couples who had civil unions in Vermont during the 1st year of that legislation. These couples were compared with 23 male and 61 female same-sex couples in their friendship circles who did not have civil unions and with 55 heterosexual married couples (1 member of each was a sibling to a member of a civil union couple). Despite the legalized nature of their relationships, civil union couples did not differ on any measure from same-sex couples who were not in civil unions. However, same-sex couples not in civil unions were more likely to have ended their relationships than same-sex civil union or heterosexual married couples. Compared with heterosexual married participants, both types of same-sex couples reported greater relationship quality, compatibility, and intimacy and lower levels of conflict. Longitudinal predictors of relationship quality at Time 2 included less conflict, greater level of outness, and a shorter relationship length for men in same-sex relationships and included less conflict and more frequent sex for women in same-sex relationships at Time 1.     

Why positive information is processed faster: the density hypothesis

The authors postulate and show a speed advantage in the processing of positive information and hypothesize that this advantage is caused by the higher density of positive information in memory: Positive information is more similar to other positive information, in comparison with the similarity of negative information to other negative information. This "density" hypothesis is supported by multidimensional scaling of evaluative stimuli and response latency experiments. The relevance and explanatory power of the hypothesis is demonstrated by secondary data analyses of prior research in the evaluative priming paradigm. The final discussion is concerned with further theoretical implications of the density hypothesis, its generality and limitations, and its relation to other theoretical conceptions and applications.     

Stalking

An anti-stalking law, now common in many western countries, took effect in Germany in November 2006 (§238 Criminal Code; see Infobox). Stalking occurs when a stalker follows a victim for weeks or months and shows molesting, threatening or attacking behavior. Through the continual pursuit, the victims feel at the least extremely insecure and at times afraid; in extreme cases, stalking can lead to psychological disturbances. Our investigations have shown that about 10–15% of males and 15–20% of females are stalking victims at some stage of their lives. This contribution describes the different forms of stalking and discusses the various motives for this behavior, as well as the psychological problems of the victim. It also provides some first thoughts on the psychotherapy of both stalkers and victims.     

On the adolescent neurosis

The author discusses the lifelong impact of adolescence in shaping the adult psyche. Some patients may appear to be as influenced by conflicts of adolescence and the individual solutions arrived at during this period as they are by conflicts and solutions of the oedipal phase, the author maintains. The subphases of early, middle, and late adolescence are discussed both in terms of a review of the psychoanalytic literature and of representative works of literary fiction. Illustrative clinical vignettes are presented as well.     

Depressive symptoms and parenting competence: An analysis of 13 regulatory processes

Mechanisms that lead depressive symptoms to undermine parenting are poorly understood. This review examines cognitive, affective, and motivational processes thought to be responsible for the impact of depressive symptoms on parenting. We present a five-step, action-control model and review 152 studies relevant to 13 regulatory processes. Evidence suggests that depressive symptoms undermine parenting because they reduce child-oriented goals, undermine attention to child input, increase negative appraisals of children and parenting competence, activate low-positive and high-negative emotion, and increase positive evaluations of coercive parenting. Yet, this review reveals significant limitations in knowledge of these processes. Evidence that they mediate depression-parenting relations is scare; important processes remain unstudied; conceptions of regulation are undifferentiated; children’s contributions are largely unexamined; moderating variables are largely unexplored; and methods fail to capture the dynamics of processing input from children. Rigorous testing of such process models holds promise for clarifying the basis of depression-related parenting problems.     

Base rate effects on the IAT

We investigated the influence of stimulus base rates on the Implicit Association Test (IAT). Using an East/West-German attitude-IAT, we demonstrated that both overall response speed and differential response speed underlying IAT effects depend on the relative frequencies of the stimulus categories. First, when those stimuli that are more common in reality also occurred more frequently in the stimulus list, response speed generally increased. Second, IAT effects increased when congruent blocks profited from the compatibility of frequency-based response biases (i.e., frequent target stimuli and frequent valence stimuli mapped onto the same response key), whereas IAT effects decreased when incongruent trial blocks profited from response compatibility. These findings demonstrate that the stimulus context moderates the magnitude of the IAT effect. Simultaneously, they highlight the need to explore the extent to which implicit measures reflect properties of the task or the environment rather than attributes of test-takers.
