Concurrent behavior: Are the interpretations mutually exclusive?

The experimental literature is replete with examples of behavior which occur concurrently with a schedule of reinforcement. These concurrent behaviors, often with similar topographies and occurring under like circumstances, may be interpreted as functionally autonomous, collateral, adjunctive, superstitious or mediating behavior. The degree to which the interaction of concurrent and schedule controlled behavior is used in the interpretation of behavior illustrated the importance of distinguishing among these interpretations by experimental procedure. The present paper reviews the characteristics of these interpretations, and discusses the experimental procedures necessary to distinguish among them. The paper concludes that the interpretations are mutually exclusive and refer to distinct behaviors, but that the distinction between any two of the interpretations requires more than one experimental procedure.     

Borderline and schizotypal personality disorders: mutually exclusive or overlapping?

This article is concerned with one aspect of the validity of DSM-III Axis II diagnoses, namely, the discriminability of borderline and schizotypal disorders. Forty-nine patients diagnosed by DSM-III criteria as borderline, schizotypal, or "mixed" personality disorders completed the Borderline Syndrome Index (BSI), an independent self-report 52-item instrument that has been shown to be reliable and to have discriminative validity. A one-way analysis of variance and a discriminant function analysis were conducted. Our major finding was that there were no significant differences among the groups on the BSI self-report test, although there were differences on clinical grounds. We discuss this in terms of "fuzzy set" theory and prototypic systems of classification.     

Can liberal perfectionism justify religious toleration? Wall on promoting and respecting

Toleration is perhaps the core commitment of liberalism, but this seemingly simple feature of liberal societies creates tension for liberal perfectionists, who are committed to justifying religious toleration primarily in terms of the goods and flourishing it promotes. Perfectionists, so it seems, should recommend restricting harmful religious practices when feasible. If such restrictions would promote liberal perfectionist values like autonomy, it is unclear how the perfectionist can object. A contemporary liberal perfectionist, Steven Wall, has advanced defense of religious toleration that grounds perfectionist toleration in an innovative account of reasons of respect. He thus defends perfectionist toleration on two grounds: (i) the appropriate manner of responding to perfectionist goods like autonomy and membership is to respect the religious choices of others; (ii) citizens can acquire reasons to respect the religious choices of others through internalizing a value-promoting moral and political code. I argue that both defenses fail. The cornerstone of both arguments is the connection Wall draws between reasons to promote value and reasons to respect it. I claim that Wall’s conception of the relationship between promoting and respecting value is inadequate. I conclude that the failure of Wall’s defense of perfectionist toleration should motivate liberal perfectionists to develop more sophisticated accounts of normative reasons. The viability of a truly liberal perfectionism depends upon such developments.     

Are attachment styles differentially related to interpersonal perfectionism and binge eating symptoms?

In the current study we aimed to examine the association between attachment styles towards father and mother, perfectionistic self-promotion (PSP), socially prescribed perfectionism (SPP), and binge eating symptoms in a sample of 328 late adolescents (mean age 17.1 years). It was examined whether anxiously and avoidantly attached adolescents would differentially cope with their insecure feelings. It was hypothesized that anxiously attached adolescents would, through hyperactivating strategies, be hypersensitive to the expectations of others. Avoidantly attached adolescents were hypothesized to present a perfect image of the self, because of their deactivating emotion regulation. Furthermore, the mediating role of perfectionism in the relation between attachment representations and binge eating symptoms was examined. Results showed that anxious attachment was significantly positively associated with PSP, SPP, and binge eating. Avoidant attachment towards mother was only positively associated with SPP, whereas avoidant attachment towards father was positively associated with PSP and binge eating. PSP fully mediated the relation between avoidant attachment towards father and binge eating. Interestingly, the current findings showed the importance of examining attachment representations towards both parents.     

Multidimensional perfectionism and assortative mating: A perfect date?

Assortative mating has been found regarding personality traits, personal attitudes and values, and cognitive abilities, but so far no study has investigated assortative mating regarding multidimensional perfectionism. A total of 422 participants from a non-commercial panel (mean age = 36.0 years) completed measures of self-oriented, other-oriented, and socially prescribed perfectionism and rated the attractiveness of four potential dating partners (“dates”): a self-oriented, an other-oriented, a socially prescribed, and a non-perfectionist date. Results showed that all perfectionist dates were seen as less attractive than the non-perfectionist date. This effect, however, was moderated by self-oriented and other-oriented perfectionism. Participants high in self-oriented perfectionism found all three perfectionist dates more attractive than participants low in self-oriented perfections. Participants high in other-oriented perfectionism found the self-oriented perfectionist date more attractive, and the non-perfectionist date less attractive than participants low in other-oriented perfectionism. The findings are discussed with respect to assortative mating, the social disconnection model of perfectionism, and the heritability of perfectionism.     

Examining cognitive performance: Do perfectionism and rumination matter?

Research has looked to possible personality constructs that can affect cognitive performance. Studies have demonstrated that working memory and attentional effectiveness can be directly related to the cognitive resources upon which one is readily able to call. Whereas limited research has examined the role of perfectionism in relation to problem solving abilities, to date, no studies have specifically examined how it may affect working memory or attention. The study’s purpose was to assess the impact of task difficulty (high, medium, or low) and personality constructs on working memory and attention. Following completion of the personality measures, participants completed the d2 test of attention and an N-back task. Results indicated that perfectionism and rumination significantly affected accuracy but not reaction time on the N-back task and that rumination significantly affected the total number of items processed on the d2 test of attention. Given the lack of elevated scores on the personality indicators within this sample, future research might examine this process in those more strongly endorsing these traits, allowing us to better ascertain the degree to which cognitive deficits may be evident.     

Are perfectionism dimensions risk factors for anxiety symptoms? A meta-analysis of 11 longitudinal studies

Background: Over 50 years of theory and research implicates perfectionism in anxiety. However, it is unclear which (if any) perfectionism dimensions are risk factors for anxiety.

Objective: To address this, we conducted a meta-analysis testing whether socially prescribed perfectionism, concern over mistakes, doubts about actions, self-oriented perfectionism, and personal standards predict increases in anxiety.

Method: Our literature search yielded 11 relevant studies for inclusion, composed of children, adolescents, undergraduates, community adults, and psychiatric patients.

Results: Meta-analysis using random-effects models revealed concern over mistakes (r^+?=?.11), doubts about actions (r^+?=?.13), and personal standards (r^+?=?.08), but not socially prescribed perfectionism or self-oriented perfectionism, displayed significant small positive relationships with follow-up anxiety, after controlling for baseline anxiety.

Conclusion: Research is needed to understand the conditions under which the connection between perfectionism and anxiety becomes stronger (e.g., stress).     

Are Feminism and Competition Compatible?

Contemporary feminist interest in the persistent underrepresentation of women in top professions suggests an implicit approval of the competition required to achieve these posts. Competition, however, seems to be in tension with feminist opposition to domination and oppression. This paper outlines the dimensions of this tension and examines three attempts to resolve the incompatibility. The first two try to separate the undesirable elements of competition from the positive by way of the competitiveness/competition and the challenge/scarcity distinctions. I argue that these distinctions fail to alleviate worries about competition, particularly in the context of the professions. Meanwhile, the third reconciliatory attempt offers a pragmatic argument for compatibilism based on the value of women's participation in the professions (and their associated competitions). Although this pragmatic argument has some merit, I argue that it significantly overestimates the amount of competition acceptable for feminist participation. The end result is that, within the context of the professions, competition remains fundamentally in tension with feminism.     

Are Truth and Reference Quasi-Disquotational?

In a number of influential papers, Hartry Fieldhas advanced an account of truth and referencethat we might dub quasi-disquotationalism. According to quasi-disquotationalism, truth and reference are to be explained in terms of disquotationand facts about what constitute a goodtranslation into our language. Field suggeststhat we might view quasi-disquotationalism aseither (a) an analysis of our ordinarytruth-theoretic concepts of reference andtruth, or (b) an account of certain otherconcepts that improve upon our ordinaryconcepts. In this paper, I argue that (i) ifthe view is understood along the lines of (a)it fails, and (ii) if it is construed along thelines of (b) it is, at best, under-motivated.     

A liberal theory of externalities?

Unlike exploitative exchanges, exchanges featuring externalities have never seemed to pose particular problems to liberal theories of justice. State interference with exchanges featuring externalities seems permissible, like it is for coercive or deceptive exchanges. This is because exchanges featuring negative externalities seem to be clear cases of the two exchanging parties harming a third one via the exchange—and thus of conduct violating the harm principle. This essay aims to put this idea into question. I will argue that exchanges featuring negative externalities are not unjust in this straightforward way, i.e. because they would constitute an instance of wrongfully causing or risking a bodily or material harm. In fact, unless we are subscribing to particularly demanding variants of liberalism—e.g. perfectionist liberalism—or unless we are exclusively focusing on borderline cases of externalities—i.e. of effects of exchanges hardly to be called externalities—there is no liberal theory of how exchanges featuring externalities are unjust.     

Are Science and Religion in Conflict?

The widely held legend of historical conflict between science and religion cannot be sustained on the basis of research. Different sciences show different relationships to religion; the physical sciences show rapprochement, whereas the human sciences often are antagonistic to religion. Reconciling science and religion by regarding each as applicable to a different domain is rejected in favor of seeing them as complementary perspectives on the same phenomena. The science and theology of human nature represents a fruitful arena for the development of this approach. A key general requirement is the epistemological reconciliation of science and religion.     

Are Events and Affordances Commensurate Terms?

In this article, I argue that the dichotomy between events and affordances as Stoffregen (target article, this issue) devises is unwarranted and potentially misleading. I challenge the notion that the role of the actor distinguishes events from affordances in any useful way. The research labeled event perception is neither less ecological nor qualitatively different from research on affordances. Instead, the main distinction is constituted by affordance being a perceptual property, whereas event pertains to a different semantic category. Nonetheless, the contemplation of these concepts, in particular an elaboration of the concept of affordance, is desperately needed.     

Are spatial and temporal attention independent?

Participants searched for one of two target letters in a rapid serial visual presentation (RSVP) sequence of 17 successive frames, each containing four letters arranged into a box around a central fixation point. In control trial blocks, the participants had no information about when or where one of the target letters would appear. In other trial blocks, visual cues were given to indicate with 100% validity either the spatial location of the target, the time at which it would be presented, or both where and when it would appear. The results showed that both types of cues were effective on their own in speeding target identification, and their effects combined additively when the cues were presented and used together. These results support a growing body of evidence indicating that early attentional selection of information in vision is independently attuned to spatial and temporal properties of the environment.     

Is perfectionism categorical or dimensional? A taxometric analysis

Considerable debate exists within the perfectionism literature regarding whether perfectionism is most accurately conceptualized as a dimensional or categorical construct. Specifically, some researchers have viewed perfectionism as a continuous construct, with extreme scores being associated with negative psychological outcomes (e.g., obsessive-compulsive disorder, eating disorders, etc.). In contrast, others have argued that two distinct forms of perfectionism exist (i.e., adaptive vs. maladaptive perfectionism) that are associated with both positive and negative outcomes. The purpose of this study was to examine the latent structure of perfectionism using taxometric procedures to determine whether perfectionism is most accurately conceptualized as taxonic (categorical) or dimensional (continuous). We applied four taxometric procedures (maximum eigenvalue [Waller & Meehl, 1998], maximum covariance [Meehl & Yonce, 1996], mean above minus below a cut [Meehl & Yonce, 1994], and latent-mode factor analysis [Waller & Meehl, 1998]) to perfectionism data collected from 2 large nonclinical samples. Results provided convergent evidence for a dimensional conceptualization of perfectionism across samples, perfectionism measures, and statistical procedures. We discuss the implications of these findings for the theory, assessment, and investigation of perfectionism are discussed.     

Are parents' and children's thinking styles related?

This study extends the investigation of the validity of Sternberg's theory of mental self-government to mainland Chinese secondary school students and their parents. The assumption of a 'socialization effect' underlying the theory was subjected to broader investigation. 232 students and their parents responded to a range of demographic questions and to the Thinking Styles Inventory which is based on Sternberg's theory. The two major findings are that (1) Sternberg's theory is valid with both samples, and (2) students' thinking styles are related not only to their personal factors, e.g., sex, grade, and self-rated abilities, but also to their parents' thinking styles. These findings have implications for school teachers and counselors as well as for parents.     

When Are Attention and Saccade Preparation Dissociated?

ABSTRACT— To understand the mechanisms of visual attention, it is crucial to know the relationship between attention and saccades. Some theories propose a close relationship, whereas others view the attention and saccade systems as completely independent. One possible way to resolve this controversy is to distinguish between the maintenance and shifting of attention. The present study used a novel paradigm that allowed simultaneous measurement of attentional allocation and saccade preparation. Saccades toward the location where attention was maintained were either facilitated or suppressed depending on the probability of making a saccade to that location and the match between the attended location and the saccade location on the previous trial. Shifting attention to another location was always associated with saccade facilitation. The findings provide a new view, demonstrating that the maintenance of attention and shifting of attention differ in their relationship to the oculomotor system.     

Are boundary extension and representational momentum related?

Boundary extension (BE) is misremembering more of a particular scene than actually presented. Representational momentum (RM) is misremembering the final position of a moving object as further along its implied trajectory. There is a sense in which both BE and RM are predictions, and the current experiments explore the possibility that these are related phenomena. We showed participants single photographs to measure baseline BE, and then approach sequences and measured BE and RM. We found significant BE and RM, and a significant interaction between baseline BE and BE following an approach sequence, but no interaction with RM. The initial evidence suggests that BE and RM are separate processes, and that BE (the establishing of spatial layout) occurs before RM (the continuation of movement) within a scene.
