Understanding and Treating Social Phobia

Social phobia, a relatively obscure disorder, is receiving increased attention due to evidence suggesting that it is more prevalent and debilitative than once thought. The purpose of this article is to help counselors better understand the nature of and treatments for this disorder. Effective behavioral and pharmacological approaches are reviewed, and counseling implications are discussed to increase counselors' confidence in providing treatment to people with social phobia.     

Chimpanzees (Pan troglodytes) can wait,when they choose to: a study with the hybrid delay task

Self-control has been studied in nonhuman animals using a variety of tasks. The inter-temporal choice (ITC) task presents choices between smaller–sooner (SS) and larger–later (LL) options. Using food amounts as rewards, this presents two problems: (a) choices of the LL option could either reflect self-control or instead result from animals’ difficulty with pointing to smaller amounts of food; (b) there is no way to verify whether the subjects would not revert their choice for the LL option, if given the opportunity to do so during the ensuing delay. To address these problems, we have recently introduced a new protocol, the hybrid delay task, which combines an initial ITC with a subsequent accumulation phase in which selection of the SS option leads to its immediate delivery, but choice of the LL option then leads to one-by-one presentation of those items that continues only as long as the subject does not eat any of the accumulated items. The choice of the LL option therefore only reflects self-control when the number of items obtained from LL choices during the accumulation phase is higher than what could be received in the SS option. Previous research with capuchin monkeys demonstrated that their apparent self-control responses in the ITC task may have overestimated their general self-control abilities, given their poor performance in the hybrid delay task. Here, chimpanzees instead demonstrated that their choices for the LL option in the ITC phase of the hybrid delay task were confirmed by their ability to sustain long delays during accumulation of LL rewards.     

Ordinal properties of subjective ratios and differences: Comment on Veit

Because nonmetric analyses of judged ratios and differences in sensory magnitude have yielded similar scales, some investigators have concluded that a single perceived relation underlies both judgment tasks. Issues rasied by this interpretation are considered in this article. Simulated data based on the assumption that subjects evaluate both perceived relations were computed for stimulus values used by Veit to investigate judgments of ratios and differences in grayness. A nonmetric analysis of both sets of simulated data in terms of a difference model yielded a solution such that each set of data was a weak monotonic transformation of the model's values, and the scale values were approximately linear with those obtained by Veit from empirical data. This result leaves open the question of whether one or two perceived relations underly the data. Ordinal properties of ratios and differences for a finite set are discussed together with their relation to systematic biases in psychophysical judgment tasks.     

The practical absolute: Fichte’s hidden poetics

The following paper argues that J.G. Fichte, despite his apparent philosophical neglect of art and aesthetics, does develop a strong, original, and coherent account of art, which not only allows the theorization of modern, non-representative art forms, but indeed anticipates Nietzsche and Heidegger in conceiving of truth in terms of art rather than scientific rationality. While the basis of Fichte’s philosophy of art is presented in the essay “On Spirit and Letter in Philosophy,” it is not developed systematically either in this text or anywhere else in his writings, but must be reconstructed through a broad consideration of all his works, including, above all, his political and economic writings. For Fichte, the art-work does not exist as an object possessing “aesthetic value” and which can, in turn, be possessed, consumed, and enjoyed through the subjective act of aesthetic experience. Rather, it involves a mode of praxis which, grounded in a radical and original power of imagination, creatively discloses possibilities for future forms of existence, experience, and political community that cannot be theoretically anticipated. While Fichte cannot himself theorize specific forms of art, since the art that concerns him belongs to the future, we can, however, retrospectively try to understand non-representational painting and non-mimetic dance as concrete realizations of Fichte’s art-work of the future. In this way, Fichte’s philosophy of art ultimately suggests an alternative to Heidegger’s understanding of the work of art as a projective institution of truth. Fichte suggests that the human body, rather than human language, is the fundamental medium of art.

Categorical processing of visual stimuli in relation to geometrical,graphemic, or lexical context

Summary Categorical perception was first demonstrated in studies of speech sounds (Liberman, Harris, Hoffman, & Griffith, 1957). The present work employed visual stimuli to explore categorical responding in relation to the context in which the stimuli were embedded. The target stimulus was a vertical line whose length was varied from 20 to 31 min (approximately) in steps of 1.2 min. Experiment 1 examined the effect of a geometrical context on the subjects' ability to discriminate between pairs of lines. The context improved performance, but produced no evidence of categorical responding. In Experiment 2 a graphemic context depressed performance, but failed to show clear evidence of categorization. By contrast, strong evidence of categorical responding was obtained in Experiment 3, in which the graphemes used in Experiment 2 were embedded in meaningful words. From this pattern of results it is argued that categorical responding is reflective not of relatively peripheral perceptual activity, but of higher-order decision processes.     

More Inaccurate But Not More Biased: Anxiety During Encoding Impairs Face Recognition Accuracy But Does Not Moderate the Own‐Ethnicity Bias

Heightened state anxiety can have a deleterious impact on memory for faces. In this paper we investigated whether anxiety: (i) moderates the own‐ethnicity bias (OEB) and (ii) impairs face recognition accuracy at the encoding or retrieval phase of an OEB face‐recognition task. Using a typical OEB task, anxiety was induced during encoding and retrieval in Experiment 1, but only during retrieval in Experiment 2. An OEB was found in both experiments, but anxiety did not moderate the OEB in either experiment. In Experiment 1, anxious participants were poorer at face recognition for both own‐ and other‐ethnicity faces. In Experiment 2 anxiety did not impair face recognition. Together, these studies suggest that anxiety impaired participants' encoding, but not retrieval, of faces. The implications of these findings are discussed.

Judgments About Sexism: A Policy Capturing Approach

Different definitions of sexism have been usedby different experimenters and little attention has beengiven to the possibility that participants' definitionsof sexism might vary across individuals and across situations, just as the definitions ofinvestigators vary. Judgments about sexism areinextricably based on individual perceptions, values,and beliefs. It would seem reasonable, therefore toexamine individual conceptions of what constitutessexism. A total of 95 primarily middle-class Caucasianparticipants (68 females, 27 males) participated inthree studies investigating what information people use in deciding whether or not a male actor issexist. Six specific categories of information (or cues)were examined: (1) comments (or lack thereof) by theactor on a female target's physical appearance, (2) unwanted or inappropriate physical contact(or lack thereof), (3) assumptions (or lack thereof)about the target's work, personality, etc., based on hergender, (4) the target being interrupted (or not) by the actor, (5) an apparent powerdifferential (or lack thereof) between the actor and thetarget, and (6) assumptions by the actor aboutappropriate gender role behaviors. A policy capturingmethodology was employed in which three different sets ofscenarios, each describing a number of interactions(called profiles) between a target and an actor, werepresented to male and female participants who rated the degree of sexism exhibited by the actor ineach scenario. Policy capturing represents anideographic approach to research in which the primaryfocus is on establishing statistical parameter estimates that describe each individual's behavior in avariety of environmental situations. Only when that isaccomplished does the researcher examine the possiblenomothetic aggregations across participants. Thus many fewer participants are required than intraditional nomothetic approaches. Each profile set useda different subset of the cues which contained eithersubtle (Study 1), overt (Study 2), or very overt (Study 3)levels of the cues. Multipleregression analysis revealed that when relatively overtacts of sexism were described, most participants hadreliable policies; that is, their judgments werepredictable from the cues. However, when relatively subtleacts of sexism were described, most participants did nothave reliable policies; that is, their judgments werenot very predictable from the cues. There were large individual differences in howparticipants weighted the importance of various cues,especially with subtle cue levels, and in participants'mean sexism ratings.     

Motion perception over long interstimulus intervais

Recent studies using moving arrays of textured micropatterns have suggested that motion percep-tion can be supported by two mechanisms, one quasilinear and sensitive to the motion of luminance-defined local texture, the other nonlinear and coding motion of contrast-defined envelopes of texture (Baker & Hess, 1998; Boulton & Baker, 1993b). Here we used similar patterns to study motion percep-tion under conditions previously shown to isolate the nonlinear mechanism (low micropattern densi-ties and positive interstimulus intervals [ISIs]). We measured direction discrimination for two-flash ap-parent motion over a much larger range of ISIs, and susceptibility to masking by incoherently moving “distractor” micropatterns. The results suggest that two nonlinear mechanisms can support motion perception under these conditions. One operates only for relatively short ISIs (less than c. 100 msec), is sensitive to small spatial displacements, and is relatively insensitive to distractor masking. The other operates over much longer ISIs, is insensitive to small spatial displacements, and is highly disrupted by distractor masking. These results are in line with previous studies suggesting that three mechanisms support motion perception.
