Global interference and spatial uncertainty in the Sustained Attention to Response Task (SART)

The Sustained Attention to Response Task (SART) is a Go–No-Go signal detection task developed to measure lapses of sustained conscious attention. In this study, we examined the impact global interference and spatial uncertainty has on SART performance. Ten participants performed either a SART (high-Go) or a traditionally formatted (low-Go) version of a global–local stimuli detection task with spatially certain and uncertain signals. Reaction time in the SART was insensitive to global interference and spatial uncertainty, whereas reaction time in the low-Go task was sensitive. Spatial uncertainty increased errors of omission in the SART, which was not expected if the SART measures mindlessness. There was a high correlation between participants’ errors of commission rate and their reaction time in the SART. The results, overall, support the view that the SART is a better measure of response strategy than lapses in sustained attention or mindlessness.     

The development of memory structure as reflected by semantic-priming effects

This study was designed to investigate the development of knowledge about categorical and associative relationships as reflected by the presence or absence of semantic priming effects. Kindergarteners and second-graders were shown pairs of pictures, one picture at a time, and asked to name each picture as rapidly and accurately as possible. Picture pairs were of four types which reflected the factorial combination of associative relatedness (high and low) with categorial relatedness (high and low). An analysis of naming times revealed a significant main effect of associative relatedness, i.e., second pictures or “target” pictures in high-associative pairs were named faster than those in low-associative pairs. This reduction in naming latency, or priming effect, was independent of developmental level. However, the effects of category relatedness varied with developmental level, i.e., target pictures in high-categorical pairs were named significantly faster than those in low pairs by second-graders, but not by kindergarteners. These findings are discussed in terms of previous estimates of children's semantic competence.     

Computerphobia

Five studies of over 450 university students presented a comprehensive picture of computer-phobia. Three research and clinically based self-report instruments were developed to measure three nearly independent dimensions of computerphobia-computer anxiety, computer attitudes, and computer cognitions and feelings. Results indicated that older students were more computer anxious, but did not have more negative attitudes, cognitions, or feelings, than did younger students. Women had more negative attitudes than did men. Feminine-identity students showed more anxiety and negative attitudes than did masculine-identity students, regardless of gender. White students had more anxiety and more positive attitudes than did nonwhite students. Computerphobia was related to other anxiety measures (mathematics, state, and trait), but was a separate construct. Experience with computer interaction did not reduce anxiety or improve attitudes. Finally, regardless of academic major, computer-anxious students showed less computer aptitude, literacy, and interest. Implications for treating computerphobia are discussed.     

The Computerphobia Reduction Program: Year 1. Program development and preliminary results

The program development and first-year results of a 3-year U.S. Department of Education Fund for the Improvement of Postsecondary Education (FIPSE) grant are described. The identification of computerphobics and the types of discomfort they experience are defined. A clinically based 5-week model computerphobia reduction and skills-acquisition program is presented. Screening and assessment measures are outlined and three treatment modules—two individual treatments (systematic desensitization and thought stopping) and an information/support group—are described. The first-year results demonstrate significant pretreatment-to-posttreatment change in anxiety, attitudes, cognitions, and feelings. Plans are discussed for further evaluation and program expansion.     

Thoughts about early pathology

In this paper, I have presented the assumption that some symptom pictures such as attachment to pain, the masochistic character, the negative therapeutic reaction, a basic depressive response, and anhedonia are rooted in a prevalence of organismic distress during the symbiotic phase. Neuroscientists taught us that early experiences are associated with the neuronal structuring of the developing brain, which then affects concurrent or subsequent reactions. In particular I followed Ginsburg's (1982) assumption of a neuronally, genetically given aggressive drive potential which influences and is influenced by early experiences, and which can interact with other gene potentials. In some patients aggressive drive components contributed to a less than harmonious basic core associated with failure of the early infant/mother interaction. Unpleasure prevailed during the symbiotic phase; aggressive energies predominated and enmeshed with the neuronal encoding, the early structuralization in both the neurophysiological and psychological meaning. Thus, the structuring of the function of internalization and the emerging self-object experience were disturbed from early on. This then continued to foster a proclivity for unstable (fusion and) diminished neutralization tendencies. As biological discharge phenomena evolve into vague psychological awareness, such an infant does not attain a sense of well-being, but rather attains a sense of "not-well-being" (Joffe and Sandler, 1965) which remains continuous or can be triggered--kindled--by any reactivating constellation, and the object is experienced as a source of unpleasure. This is in line with Mahler's bad mother and bad self-introjects. Primary narcissism has not evolved well or, said differently, is invested more with aggressive than with libidinal cathexis and is in an unfortunate association or balance with primary masochism. Aggressive drive components subsequently color fantasies, readiness for and severity of conflicts. The aggressivization of self-feelings and of the function of internalization with its influence on--and exacerbation of--the rapprochement crisis is traced into later symptomatology. The basic pathology as described in this paper then compounds the oedipally derived problems.     

ON THE EFFECTS OF NONCONTINGENT DELIVERY OF DIFFERING MAGNITUDES OF REINFORCEMENT

We conducted a parametric analysis of response suppression associated with different magnitudes of noncontingent reinforcement (NCR). Participants were 5 adults with severe or profound mental retardation who engaged in a manual response that was reinforced on variable-ratio schedules during baseline. Participants were then exposed to NCR via multielement and reversal designs. The fixed-time schedules were kept constant while the magnitude of the reinforcing stimulus was varied across three levels (low, medium, and high). Results showed that high-magnitude NCR schedules produced large and consistent reductions in response rates, medium-magnitude schedules produced less consistent and smaller reductions, and low-magnitude schedules produced little or no effect on responding. These results suggest that (a) NCR affects responding by altering an establishing operation (i.e., attenuating a deprivation state) rather than through extinction, and (b) magnitude of reinforcement is an important variable in determining the effectiveness of NCR.
