The origin of exemplar effects in rule-driven categorization

S. W. Allen and L. R. Brooks (1991) have shown that exemplar memory can affect categorization even when participants are provided with a classification rule. G. Regehr and L. R. Brooks (1993) argued that stimuli must be individuated for such effects to occur. In this study, the authors further analyze the conditions that yield exemplar effects in this rule application paradigm. The results of Experiments 1-3 show that interchangeable attributes, which are not part of the rule, influence categorization only when attention is explicitly drawn on them. Experiment 4 shows that exemplar effects can occur in an incidental learning condition, whether stimulus individuation is preserved or not. The authors conclude that the influence of exemplar learning in rule-driven categorization stems from the attributes specified in the rule or in the instructions, not from the stimulus gestalts.     

The epigenesis of stuttering

This paper examines the data on which the Demands and Capacities Model (DCM) is based with the purpose of identifying areas where future research might determine consilience among genetic influences at the physiological, behavioral, and cultural levels. The determination of consilience across different levels would tend to validate the genetic influence on stuttering, but more importantly it would also sharpen the focus of researchers interested in the various possible expressions that genetic influences might have and the way in which they influence the development of the disorder.

Educational objectives: The reader will (1) learn about the distinction, as outlined in the DCM, between environmental/contextual influences on stuttering development and intrinsic/genetic influences on stuttering development; (2) learn about the concept of consilience and its usefulness in conferring validity on parallel constructs at the physiological, behavioral, and cultural levels of stuttering theory; and (3) be able to identify potential areas for research that might help in refining our understanding of the genetic influences on stuttering development.     

Supervisees' perspectives on the contribution of supervision to psychotherapy outcomes

Objective

The aim of this study was to examine supervisees' perspectives about the contribution of two predefined aspects of supervision, supervisory bond (SB) and didactic input of supervisor (DI), to their ascribed outcome of therapy.

Method

Supervisees anonymously assessed the SB, supervisors' DI and their contribution to therapy outcome. Assessment was quantitative and qualitative. The supervisory aspects were assessed using a questionnaire constructed for this study. Perceived contribution was evaluated by two scaled questions, and themes generated by an open question. Supervisees (n = 111) evaluated 16 supervisors and supervision’s contribution to psychotherapy outcomes of 111 clients.

Findings

Hierarchical regression showed that supervisees' age, supervisors' status and frequency of supervision accounted for 24% of the variance ascribed to outcome. SB and DI accounted for 51% of the variance. These values, which are higher than reported in the literature, may be attributed to the assessment of predefined aspects of supervision by the same assessor. Thematic analysis of the didactic input produced more themes than for the supervisory bond.

Conclusion

Sociodemographic variables and supervisory relationship variables determine supervisees' evaluations of supervision’s contribution to outcome.

Implications for practice

Training and supervision may benefit from information obtained from quantitative and qualitative measures regarding these and other predefined variables related to supervision. The in-depth look at views and experiences shared by supervisees may advance training, practice and research.     

Talking to a (Segregation) Wall: Intergroup Contact and Attitudes Toward Normalization Among Palestinians From the Occupied Territories

This article examines how Palestinians' intergroup contact experiences relate to their attitudes towards interactions with Israelis (i.e., normalization). We draw on four recent advances in intergroup contact literature. First, recent research indicates that positive contact can impede disadvantaged groups' motivation to challenge inequalities. Second, increased endorsement of normalization mediates this sedative effect of positive contact on motivation to resist in the West Bank. Third, negative contact has been related to increased motivation for social change. Fourth, institutions and societal norms shape the meaning of intergroup contact and its effect on intergroup relations. We hypothesize that negative experiences at checkpoints can act as reminders of institutionalized inequalities and thus attenuate sedative effects. Furthermore, we explore the contextual boundary conditions of such reminder effects. Analyses of cross-sectional survey conducted among a representative sample (N = 1,000) in the West Bank including Jerusalem showed that (1) positive intergroup contact related to normalization endorsement (sedative effect), (2) negative intergroup contact related to decreased normalization endorsement (mobilizing effect), and (3) negative contact experiences (at checkpoints) canceled out the effect of positive contact (reminder effect), but only in Jerusalem. Results suggest that the impacts of intergroup contact need to be interpreted in light of institutionalized forms of group inequality and segregation.     

Nietzsche's Critique of Pure Altruism—Developing an Argument from Human,All Too Human

Abstract

Nietzsche often appears, especially in his writings from the middle period, to endorse psychological egoism, namely the claim that all actions are motivated by, and are for the sake of, the agent’s own self-interest. I argue that Nietzsche’s position in Human, All Too Human (Cambridge: Cambridge University Press, 1986) should not be so understood. Rather, he is claiming, more weakly and more plausibly, that no action is entirely unegoistic, entirely free of egoistic motivations. Thus some actions might be motivated both by egoistic and unegoistic motives, on his view. Nietzsche’s argument may, in other words, be understood to be directed specifically against Schopenhauer’s portrayal of moral motivation, as pure, entirely unalloyed altruism, to show that this sort of action is impossible, not to rule out the possibility of any altruistic motive whatsoever. In light of Schopenahuer’s moral psychology, to which Nietzsche to some extent adhered at that time, I develop a concept of motivation and reconstruct Nietzsche’s argument.     

Amor Fati as Practice: How to Love Fate

On the basis of an interpretation of key passages in The Gay Science, this paper examines Nietzsche's idea of amor fati—love of fate. Nietzsche's idea of amor fati involves the wish to be able to learn how to see things as beautiful. This gives the impression that amor, love, is supposed to play some role in the beautification of fate. But Nietzsche also explains amor fati in relation to his desire to be a devoted “Yes‐sayer.” This pulls the interpretation of amor in a different direction; for now it seems as if the love Nietzsche wants to cultivate is supposed to be expressed in a positive, affirmative attitude toward one's fate. How to think this duality under the single idea of amor fati? I develop a novel reading of amor fati as a form of practice, as something that we can do, and explain in its light how the two moments of love are to be brought together. The relation of amor fati to the “Eternal Recurrence of the Same” is also addressed: mastering the practice of amor fati can enable one to pass successfully the test of the Eternal Recurrence of the Same.     

Non-Suicidal Self-Injury and Adolescents Attachment with Peers and Mother: The Mediating Role of Identity Synthesis and Confusion

Non-suicidal self-injury (NSSI) is highly prevalent in adolescents. Secure attachment with family and peers can reduce vulnerability to NSSI and can optimize the outcomes of developmental challenges such as identity formation. Problems experienced in these developmental processes and contexts can increase vulnerability to NSSI. Hence, the present study examined associations between attachment with mother and peers, identity formation, and NSSI, using self-report questionnaires in 528 high school students (Mean age = 15.0 years, SD = 1.84, 11–19 years, 50.4 % females). The lifetime prevalence of NSSI was found to be 14.2 %. Mediation analyses indicated that peer trust had a significant negative indirect effect on NSSI via identity synthesis and confusion. The positive association between peer alienation and NSSI was partially mediated by a lack of identity synthesis. Further, the pathways from maternal trust and alienation to NSSI were fully mediated by both identity confusion and synthesis. Clinical implications and suggestions for future research are discussed.     

Three symbol ungrounding problems: Abstract concepts and the future of embodied cognition

A great deal of research has focused on the question of whether or not concepts are embodied as a rule. Supporters of embodiment have pointed to studies that implicate affective and sensorimotor systems in cognitive tasks, while critics of embodiment have offered nonembodied explanations of these results and pointed to studies that implicate amodal systems. Abstract concepts have tended to be viewed as an important test case in this polemical debate. This essay argues that we need to move beyond a pretheoretical notion of abstraction. Against the background of current research and theory, abstract concepts do not pose a single, unified problem for embodied cognition but, instead, three distinct problems: the problem of generalization, the problem of flexibility, and the problem of disembodiment. Identifying these problems provides a conceptual framework for critically evaluating, and perhaps improving upon, recent theoretical proposals.
