Beacons,breasts, symbols,sex and cancer

Since the 1950's effective control of conception has allowed modern men and women to differentiate procreational from recreational sexual exchange. What is considered highly erotic has differed widely through time and in various cultures. In the U.S. the female breast has come to mean far more than nurturing an infant. Sexuality symbolizes youth, attractiveness, desirability and as such is used for effective commercial marketing. The reality of cancer remains to be dealt with in health care at a physical level but more is needed to assist the emotional adjustment of affected women and their partners. Brief sex therapy for sex symptoms is outlined.     

Allocation of attention, reading skills, and deafness.

Brannan and Williams (1987) found that poor readers cannot successfully utilize parafoveal cues to identify letter targets. Whether a similar deficit in the use of cue information occurs in deaf poor readers and whether it is only specific to processes that capture attention automatically were investigated in congenitally deaf young adults classified as poor or good readers and hearing controls classified as good readers. Subjects were presented with central or parafoveal cues that varied in cue validity probability, followed by letter targets presented to the left or right of fixation. The reaction time data analyses showed significant main effects for cue type and cue location and significant interactions among cue type, cue location, cue validity probability, and visual field. No significant main effect or interactions involving groups were found. These results raise the possibility that reading difficulties associated with deafness do no involve a deficit in the visual attentional system of deaf people. They also confirm that parafoveal cues are more effective than central cues in capturing attention.     

The benefit of symbols: monkeys show linear, human-like, accuracy when using symbols to represent scalar value

When humans and animals estimate numbers of items, their error rate is proportional to the number. To date, however, only humans show the capacity to represent large numbers symbolically, which endows them with increased precision, especially for large numbers, and with tools for manipulating numbers. This ability depends critically on our capacity to acquire and represent explicit symbols. Here we show that when rhesus monkeys are trained to use an explicit symbol system, they too show more precise, and linear, scaling than they do using a one-to-one corresponding numerosity representation. We also found that when taught two different types of representations for reward amount, the monkeys systematically undervalued the less precise representation. The results indicate that monkeys, like humans, can learn alternative mechanisms for representing a single value scale and that performance variability and relative value depend on the distinguishability of each representation.     

Blind and constructive patriotism,national symbols and outgroup attitudes

We examined whether there is a relationship between the different forms patriotism can take (i.e., blind vs. constructive) and different representations of one's own nation. We considered two types of national symbols representing the nation in terms of confrontation between groups (polarized symbols) and as a unique entity (unpolarized symbols). In Study 1 we found that blind patriotism was positively associated with the degree to which individuals perceived their nation through confrontation whereas constructive patriotism was positively associated with the degree to which individuals perceived their nation as unique entity. In Study 2 we tested how the relationship between blind patriotism and outgroup attitudes changed when the nation was defined either through confrontation or as a unique entity. The results emphasize the essential role of the specific meaning associated to the nation when studying patriotism and its relation to outgroup attitudes.     

The contextually controlled, feature-mediated classification of symbols

The classification of names of people or objects based on the features acquired by the names and the sorting instructions provided is a commonplace occurrence. For example, given the names Renoir, Pollock, James and Voltaire the average adult would be able to classify them differentially based on the instruction to classify them based on vocation or nationality. In general, such a repertoire reflects the reclassification of symbols (i.e, the names of individuals) in terms of contextual cues (instructions to sort by vocation or nationality) and the features acquired by the symbols (the specific nationalities and vocations). The present experiment studied this phenomenon with the use of arbitrary stimuli that did not have clear preexperimental associations. Two of 4 participants classified the symbols into different equivalence classes based on the prevailing contextual cues and the features that had been acquired by the symbols. Using an ABA reversal design we then demonstrated that 1 participant classified the symbols in accordance with the contextual cues and acquired features when present, but not in the absence of the contextual cues. A 3rd participant showed symbol classification that differed from that predicted by the procedures, and the 4th classified the symbols based on one set of features but not on context. These data describe one set of conditions that could account for the establishment of complex classification repertoires that occur in natural settings.     

Relationships among spatial skills, communication skills, and field independence in deaf students

The hypotheses that deaf students would be more field-dependent than hearing students and that their competence in communication skills would be positively related to field-independence were supported for a group of 77 male and 67 female deaf students. Step-wise multiple regression analyses of the data showed that for females spatial skills followed by communication skills were significant predictors of field-independence; for males spatial skills followed by the extent of hearing loss were significant predictors of field-independence. Sex differences found on tests of field-independence and spatial relations were consistent with those obtained from the hearing population. It was suggested that socialization experiences and competence in communication skills may influence development of field-independence in deaf students.     

Social skills, social outcomes, and cognitive features of childhood social phobia.

Social skills, social outcomes, self-talk, outcome expectancies, and self-evaluation of performance during social-evaluative tasks were examined with 27 clinically diagnosed social phobic children ages 7-14 and a matched nonclinical group. Results showed that, compared with their nonanxious peers, social phobic children demonstrated lower expected performance and a higher level of negative self-talk on social-evaluative tasks. In addition, social phobic children showed social skills deficits as assessed by self- and parent report, an assertiveness questionnaire, and direct behavioral observation. Furthermore, compared with the control group, social phobic children were rated by themselves and others as significantly less socially competent with peers and were found to be less likely to receive positive outcomes from peers during behavioral observation. Implications for the assessment and treatment of childhood social phobia are discussed.
