Reflectivity, Reflection, and Counter-Education

This article sets forward a new concept of reflection, to be contrasted with more usual reading of the concept for which we use the term `reflectivity'. The contrast is related to a distinction between normalizing education and counter-education. We claim that within the framework of normalizing education there is no room for reflection, but only for reflectivity. In contrast to reflectivity, reflection manifests a struggle of the subject against the effects of power which govern the constitution of her conceptual apparatus, her knowledge, her consciousness and her limitations and possibilities for successful functioning. Reflectivity re-presents the hegemonic realm of self-evidence and the productive violence of social and cultural order. Reflection, by contrast, aims to challenge the supposedly self-evident and the present order of things. Reflection aims at transcendence and represents a moral commitment in respect of the otherness of the Other, which power relations in every realm of self-evidence oblige us to neglect, to destroy or consume. Transcendence is a concrete utopia, and so is the subject in her nonrepressive communication with the Other: they are part and parcel of our present possibilities, sometimes in microscopic arenas, struggled for, and from time to time even realized.     

Selective adaptation of monocular and binocular neurons in human vision

Psychophysical techniques were used to examine how subpopulations of visual neurons varying in their ocular dominance interacted in determining performance on a visual task. Using an asymmetric alternating adaptation of the left and right eyes, we manipulated the sensitivity of monocularly driven neurons while keeping the sensitivity of binocularly driven neurons constant. Relative threshold elevations were measured in the left eye, right eye, and both eyes of five observers following different ratios of alternating adaptation. It was found that whereas monocularly measured aftereffects varied monotonically as a function of the adaptation duration of the measured eye, the magnitude of the binocularly measured aftereffect remained constant regardless of how the adaptation was divided between the two eyes. This suggests that neurons differing in their ocular dominance pool their activity in determining sensitivity to a test target.     

Dichoptic reading: The role of meaning in binocular rivalry

These experiments sought to determine whether meaning influences the predominance of one eye during binocular rivalry. In Experiment 1, observers tried to read meaningful text under conditions in which different text streams were viewed by the two eyes, a situation mimicking the classic dichotic listening paradigm. Dichoptic reading proved impossible even when the text streams were printed in different fonts or when one eye received a 5-sec advantage. Under non-rivalry conditions, the observers were able to read text presented at twice the rate used for dichoptic testing, indicating that cognitive overload does not limit performance under conditions of rivalry. In Experiment 2, observers were required to detect repeated presentations of a probe target within a string of characters presented to one eye. Although this task was easily performed under monocular viewing conditions, it proved difficult when the two eyes received dissimilar character strings. This was true regardless of whether the probed eye viewed nonsense strings, real words, or meaningful text. In a condition designed to encourage semantic processing of one eye’s view, the observers were required to detect animal names as well as to detect the probe target. Performance remained inferior to that measured under monocular conditions. Even the observer’s own name proved insufficient to influence the predominance of one eye under conditions of dichoptic stimulation. When two text strings were physically superimposed and viewed monocularly, essentially no probes were detected, indicating that the failure to see some probes during rivalry reflects a limitation unique to dichoptic viewing. These results contradict theories attributing binocular rivalry to an attentional process that operates on monocular inputs that have received refined analysis. This conclusion may be limited to rival stimuli whose meaning is defined linguistically, not structurally.     

Socialization Tactics and Newcomer Information Acquisition

Research on organizational socialization has usually focused on what organizations do to socialize newcomers or on what newcomers do to socialize themselves. The purpose of this study was to integrate these two perspectives of socialization by investigating the relationships between socialization tactics, newcomers' information acquisition (i.e. feedback and observation) and socialization outcomes. Consistent with previous research, socialization tactics and information acquisition were related to socialization outcomes. Furthermore, institutionalized socialization was positively related to the frequency of newcomers' feedback and observation and the frequency of newcomers' feedback and observation was found to mediate several of the relationships between socialization tactics and outcomes. These results suggest that what newcomers can do to socialize themselves (e.g. acquire information through feedback and observation) is partly a function of what organizations do to socialize newcomers (e.g. the use of specific socialization tactics). The implications of these findings are discussed for the development of a more complete and integrated theory of organizational socialization.     

On the Dimensionality of Jones' (1986) Measures of Organizational Socialization Tactics

One of the most theoretically developed models of organizational socialization is Van Maanen and Schein's (1979) typology of six tactics. Jones' (1986) operationalization of these tactics has been used in most survey studies of the Van Maanen and Schein model. However, questions remain concerning the dimensionality of the operationalization. Self-report data from business school graduates after 4 months (n = 295) and 10 months (n = 222) on the job indicate that: (1) a 6-factor model better approximates the covariance matrix of the socialization items than do competing 1- and 3-factor models, (2) the 6-factor model better predicts certain work adjustment variables than the 3-factor model, and the 3-factor model better predicts certain variables than the 1-factor model, and (3) the collective, formal, sequential, fixed, serial, and investiture tactics are positively interrelated, suggesting a structured program of early work experience.     

Clinical Geropsychology: Implications for Practice in Medical Settings

Older adults are a rapidly growing segment of the population, who have high rates of chronic illness and who utilize health care resources heavily. Psychologists must become better prepared to work with older patients in geriatric settings, including geriatric assessment units, memory disorders clinics, and nursing homes. In addition, all psychologists will increasingly encounter older patients in environments such as primary care clinics, rehabilitation settings, and disease management programs focusing on problems that are prevalent in older patients (e.g., cancer, diabetes). Suggestions are offered for adaptation of usual clinical practice to address the special needs of older patients and their families, and recommendations made for advancing and expanding the practice of clinical geropsychology.     

Antidepressant medication in the treatment of agoraphobia: A critical review

The present article critically examines research on the use of antidepressants in treating agoraphobia. A number of studies have shown certain classes of antidepressant medication, namely tricyclic antidepressants and MAO inhibitors, to have beneficial effects on certain aspects of the agoraphobic syndrome. However, these studies must be interpreted with caution in light of two major methodological shortcomings, i.e. sole reliance on paper and pencil outcome indices and the confounding of the pharmacological effects of the drug with exposure to feared situations. Recent research, aimed at correcting for these methodological problems, seriously question the efficacy of antidepressant pharmacotherapy by itself as a treatment for agoraphobia. Moreover, it is argued that the disadvantages of drug treatments namely agoraphobics' reluctance to take medication, physical side effects and relapse upon withdrawal of the medication, caution against their routine use in clinical practice.     

Binocular rivalry and semantic processing: out of sight, out of mind

Previous studies of binocular rivalry have shown that some aspects of a phenomenally suppressed stimulus remain available for visual analysis. The question remains, however, whether this analysis extends to the case of semantic information. This experiment examines that question using a semantic-priming paradigm in which prime words were briefly flashed to an eye during either dominance or suppression phases of binocular rivalry. Reaction times on a lexical-decision task were significantly shortened (the semantic-priming effect) only when prime words were presented to an eye during dominance; suppression acted to impair word recognition and to eliminate semantic priming. These results are inconsistent with certain cognitive models of binocular rivalry.     

Binocular summation of equal-energy flashes of unequal duration

To determine if binocular summation occurs when increment flashes are of equal energy (Bloch’s law) but unequal in luminance-duration parameters, three Ss made temporal forced-choice judgments: (1) monocularly, (2) binocularly when the flashes to each eye were identical, (3) binocularly when the flashes to each eye were of equal energy but different in terms of their luminance and duration parameters, and (4) binocularly when flashes to each eye were separated by 100 msec. Binocular detection rates were consistently superior to monocular detection rates. Similarity in performance between Conditions 2 and 3 indicates that the binocular visual system responds only to the total energy of each monocular flash. The data from two Ss reveal that binocular performance was greater than that predicted on the basis of probability summation.     

Further developments in binocular summation

This paper reviews experiments that bear on the issue of binocular summation, the superiority of binocular over monocular viewing on various visual tasks covering studies published since the appearance of a previous review of this literature by Blake and Fox (1973). The experiments are grouped into three main categories—those that deal with the specificity of binocular summation (i.e., the extent to which inputs to the two eyes must coincide spatially and temporally), those that study binocular summation on suprathreshold tasks, and those that correlate binocular summation with other aspects of binocular function. The last section of the paper critically reviews several models of binocular summation.
