Response versus place learning by human infants

Two cross-setional studies examined how infants learn the location of visual events. In Experiment 1, infants of 4, 8, and 12 mo of age learned to turn one way to view a novel pattern. In a subsequent transfer task, they were rotated to face the opposite side of the room. The 4-mo-old infants tended to err by repeating their previously learned response, but within 16-20 trials their performance was comparable to the higher levels maintained by the older infants. These results suggest that young infants learn the location of the pattern primarily in terms of response cues, whereas older infants employ both response cues and place cues. Experiment 2 was designed to independently assess the use of response cues and place cues by infants of 4, 8, 12, and 16 mo of age. All infants were able to rapidly learn and remember the location of the novel pattern when they were given response cues. There was a gradual emergence of place-cue use associated with age. It is suggested that the decrease in infant egocentricity in such spatial localization tasks may in fact reflect an age-related increase in the variety of reliable cues responded to by infants.     

Secondary task modality, expectancy, and the measurement of attentional capacity

Previous studies have obtained conflicting evidence regarding the effect of probe modality when a secondary probe task is used to measure attentional demands of a primary letter-matching task. The present experiments found no difference in the shape of the probe reaction time functions for auditory and visual probes as long as probe modality was known. When probes "unexpectedly" occurred in the modality that was different from the majority of the probes, differences were obtained. Only the unexpected auditory function changed, shape relative to the others, with reaction time to probes that occurred early in the matching task sequence being increased. The results are interpreted as supporting a role of attentional capacity in the activation of structures that accept relevant sensory input.     

Drug-preexposure effects in flavor-aversion learning: associative interference by conditioned environmental stimuli

Previous research has documented that exposure to a drug reduces the ability of the drug to support subsequent flavor-aversion learning. The four experiments reported here examined the hypothesis that this drug-preexposure effect is due to associative interference from environmental stimuli associated with the drug effects during preexposure. When distinctive environmental stimuli (confinement in a black compartment) were present during drug preexposure, these stimuli significantly disrupted subsequent flavor-aversion learning. Furthermore, flavor conditioning was not significantly disrupted when drug preexposure occurred in the absence of salient environmental stimuli or when the previously conditioned environmental stimuli were extinguished prior to flavor conditioning. It is significant, and in contrast to other published research, that flavor conditioning was not disrupted when the distinctive cues paired with the drug during preexposure were absent at the time of the flavor-drug pairing. These results are thus consistent with results from conventional studies of stimulus blocking and suggest that associative processes can play a major role in the drug-preexposure effect.     

Control of instrumental behavior by deprivation stimuli

In Experiment 1, rats were given one trial per day in a straight alley under food deprivation on half of the trials and under water deprivation on the other half. Wet mash was available in the goal box under food deprivation for Group H and under water deprivation for Group T, the other deprivation being nonrewarded for each group. After 15--18 trials both groups ran significantly faster on their rewarded than on their nonrewarded deprivation days. A third group showed that random variation of alley color retarded formation of the discrimination. A fourth group was run in a conditional discrimination in which under food deprivation wet mash was available in a black alley, nonreward in a white alley, and vice versa under water deprivation. This group took 114 trials to begin running significantly faster in their rewarded than in their nonrewarded alley under each deprivation. In Experiment 2, it was shown that prior learning about deprivation cues "blocks" learning about alley color when alley color is subsequently presented in compound with the deprivation cue but that when both alley color and deprivation cues are relevant from the start of training, the rat learns about both cues. It is suggested that previous studies have underestimated the importance of deprivation cues by using conditional discrimination designs, choice measures rather than speeds, and parameters that are not optimal for discrimination learning.     

Spatial localization under conflict conditions: is there a single explanation?

Visual--auditory (VA) and visual--proprioceptive (VP) localization conflict paradigms were varied to explore the comparability of the conflict situations. In experiment 1 various attempts were made to decrease the dominance of visual information over proprioceptive and auditory target information. Pairing auditory with proprioceptive information against conflicting visual information did not lessen the visual dominance, nor did dimming the visual field. A 'cognitive' manipulation, in which the subject was led to doubt the reliability of the visual information, reduced visual dominance over audition but not visual dominance over proprioception. This difference between the two conflict situations was further explored and corroborated in experiment 2. In experiment 3 no attempt was made to lead the subject to believe that paired discrepant targets were related, and the visual dominance of audition was strong while the visual dominance of proprioception did not occur. The apparent differences between the VA and VP conflict situations are discussed with regard to the feability of generating a unitary explanation of localization conflict results. Several further factors are discussed that must be explored before undertaking such a unitary formulation.     

Patterns of figurative language competence in adult speakers

Summary In an attempt to discover patterns of adult figurative language use, preference and comprehension, 30 Ss were asked to complete 4 different tasks: a composition, a test of simile preference, a test of simile production, and a test of metaphoric comprehension. Each test provided scores for both novel and clichéed usage. The composition task was also scored for total words while preference and production tasks were scored for literal usage, thus producing a total of 11 dependent variables across the complete set of tasks.Results revealed that Ss selected a higher number of novel figures under choice relative to production conditions. Correlational results revealed relationships across all 4 tasks for the categories of novel and frozen usage although certain tasks (i.e., simile preference and production) were more sensitive to novel diction while others (comprehension) were more sensitive to frozen diction. Within-task correlations, on the other hand, showed unique patterns for each of the tasks. Factor analyses of these correlations were found to produce a series of consistent three-factor solutions with the first of these factors concerned primarily with novel diction, the second with both novel and frozen comprehension, and the third primarily with frozen diction.Taken in combination, present results were interpreted to mean that while the distinction between novel and frozen is a meaningful one, specific task requirements can and do moderate the pattern of relationships obtained. This suggests that figurative language competence may not be a unitary process but one that is strongly affected by specific task and situational constraints and that future work, both methodological and theoretical, must take these factors into account.     

Entry-Level Employment Prospects for Women in College-Student Personnel Work

Women are no longer underrepresented in student-personnel preparation programs. Although this situation is noteworthy, it may not be without potentially frustrating consequences for the increased number of female master's degree graduates who are seeking a limited number of entry-level positions. Whether the increase in women will have deleterious effects on placement remains to be seen. In the meantime, women (and men) should be made aware of the inherent free-market employment risks when contemplating a career in student-personnel work.     

Generic Models of Counseling Supervision: Counseling/Instruction Dichotomy and Consultation Metamodel

Major conceptual models for counseling supervision are described and compared: supervision as a counseling analog, as an instruction or teaching analog, and as a role that includes counseling and teaching aspects. Although each of these approaches avails supervisors of familiar roles, none adequately provides the scope and utility required of a model for such a complex function. Thus, a higher order metamodal, supervision as consultation, is presented, and this consultation metamodel is related to the psychoeducational model for counseling psychology.
