Emotional mood and memory in young children

Two experiments examined affect-dependent memory with preschool/kindergarten and third-grade children. A two-list intentional learning procedure was used to assess the effects of the congruent versus incongruent relationship between affect (happy vs sad) during initial list learning and affect (happy vs sad) during a delayed recall test. When induction of emotional mood was preceded by relaxation exercises in Experiment 1, no evidence of affect dependence was observed. When the relaxation procedure was omitted in Experiment 2, the affect-dependent pattern was obtained in both free recall and cued recall for both age groups. The results of Experiment 2 show that affect-dependent memory is a reasonably robust phenomenon in children and that hypnosis is not necessary for its appearance. However, the phenomenon is apparently absent under conditions of relaxation, a result consistent with two-factor theories of emotion.     

Nonconsummatory and consummatory behavioral CRs elicited by lithium- and amphetamine-paired flavors

Various behavioral CRs elicited by saccharin solution previously paired with either lithium or amphetamine were measured in a series of four experiments. With one conditioning trial, lithium (Experiment 1), but not amphetamine (Experiment 2), produced nonconsummatory behavioral evidence of conditioning in the form of chin-rub CRs; both drugs, however, produced strong flavor aversions. With 3 conditioning trials, lithium- and amphetamine-paired flavors elicited a pattern of agitated activity, characterized by increased general activity, rearing duration, and body temperature, when the flavor was forcibly presented through an intraoral cannula (Experiment 3). When the flavor was presented in a single-bottle test (Experiment 4), 3 conditioning trials produced a similar pattern of agitated activity characterized by increased general activity, rearing (duration and frequency), stretching (duration and frequency), and limb flicking. Although both drugs supported the pattern of increased agitation-related CRs, only the lithium-paired flavors elicited chin-rub CRs (Experiments 1, 3, and 4). The difference between the drug conditions was not the result of a greater saccharin aversion in the lithium-conditioned group than in the amphetamine-conditioned group (Experiment 4). The results are related to findings that suggest that flavor aversions are mediated by a shift in the hedonic properties of the drug-paired flavors.     

The choice reaction times of single and dual jointed actions

The choice reaction times of dual (elbow and wrist) and single (elbow) jointed movements were measured using ‘mixed’ (dual and single) and ‘matched’ (both dual or both single) response pairings. Although subjects found it more difficult to execute dual jointed actions (as shown by error rate), there was no concomitant prolongation of latencies for acceptable responses. In the light of these findings, the utility of CRT as an index of motor programming complexity, and the claim that pre-programming of responses is precluded with CRT testing, were discussed.     

Timing in the performance of Erik Satie's ‘Vexations’

In traditional studies of single cue probability learning the subject's errors and the covariation he/she establishes between the judgments and the cue (cue dependency) are confounded. Learning results in increased cue dependency which is necessarily accompanied by decreasing errors. This paper presents a method for disentangling errors from cue dependency. This is done by (1) making the criterion contingent upon the judgments instead of the cue, and (2) giving standard instructions, implying that the cue is informative about the criterion. In this way errors are controlled independently of any covariation that the subject may create between the cue and the judgments, and indirectly between the cue and the criterion (task regularity). The paper examines whether subjects aim at small errors or task-regularity when the task does not allow them to do both. It was found that error reduction does occur only when task-regularity can be maintained. Conclusion: task regularity, and thus cue-dependency, has priority to error reduction under the standard conditions used in single cue probability learning experiments. The study may be viewed as an example of conditions under which a cue illusion (false beliefs in the validity of a cue) arises.     

Cerebral lateralization, preferred cognitive mode, and reading ability in normal children

In a sample of 105 children (aged 6 to 12), a stylistic preference for a verbal approach to problem-solving correlated positively with reading ability (independently of age) and degree of right-ear advantage in the report of dichotic stop consonant-vowel syllables (but not with verbal intelligence or hand preference). Verbal strategic preference may: (1) foster the acquisition of reading skill, and (2) bias attention toward input from the right by generating differential left-hemisphere activation.     

Thematic elaboration and proximity in childrens recall, organization, and long-term retention of pictorial materials.

Preschool and fifth-grade children were asked to learn and recall lists of nine pictures of common objects in which the thematic relationship and the physical proximity of subsets of items were varied. Five presentation conditions (lists) were employed: (1) subgroups of three items simultaneously presented with an explicit theme, (2) the same items as in (1) but randomly arranged in the subset, (3) unrelated items presented simultaneously in groups of three, (4) nine items presented successively but temporally blocked in subgroups of three, and (5) nine items displayed successively in a random arrangement. Recall and clustering scores indicated that the older children spontaneously elaborated pictures when subsets of items were presented simultaneously and when these items formed a natural theme. The preschool children failed to elaborate, responding more on the basis of the proximity of the items. Proximity was a potent recall cue for both age groups. Long-term tests, carried out after one week, showed good retention, the output organization of which closely paralleled that observed during original learning.     

Effectiveness of a brief counseling intervention in stimulating vocational exploration

The intervention procedures used in this study, a brief report of vocational interest scores and small group sessions on vocational planning, were designed to encourage girls to consider the full range of occupations, unrestricted by sex-role stereotypes. In each of three schools, ninth-grade girls with average academic ability or above were randomly assigned to an intervention group (N = 195) and a control group (N = 195). Analyses of 1- and 3-month outcome data indicated that the intervention stimulated occupational exploration and increased congruence between occupational preferences and measured interests. Outcomes differed according to interest type, thus suggesting that certain students may need more counselor attention than others.     

The cognitive and neurological basis of developmental dyslexia: a theoretical framework and review.

It is argued that developmental dyslexics have difficulty in accessing the meaning of written words via phonological recoding, although they can successfully access meaning by a direct visual route. This difficulty with phonological recording is explained in terms of a short-term memory deficit. It is suggested that developmental dyslexia is a genetically-based dysfunction of the inferior parietal lobule and evidence is reviewed that this region is important in both reading and short-term memory. Implications for remedial instruction are discussed.     

The development of analogical reasoning processes.

Two experiments were conducted to test the generalizability to children of a theory of analogical reasoning processes originally proposed for adults (R. J. Sternberg, Psychological Review, 1977a, 84, 353–378; R. J. Sternberg, Intelligence, information processing, and analogical reasoning: The componential analysis of human abilities, Hillsdale, N.J.: Lawrence Erlbaum Associates, 1977b) and to examine the development of analogical reasoning processes in terms of five proposed sources of cognitive development: (a) availability of component operations; (b) strategy for combining multiple component operation; (c) strategy for combining multiple executions of the same component operation; (d) consistency in use of strategy; (e) component-operation latency and difficulty. Between 15 and 21 subjects in each of grades 2, 4, 6, and adulthood (ages 8, 10, 12, and 19 years, respectively) were tested in their ability to solve analogies of systematically varied difficulty. Performance was measured in terms of latencies for items solved correctly, latencies for all items solved, and error rates. A slightly modified version of the Stenberg, 1977(a), Stenberg, 1977(b) theory was found to be applicable to the data for each of the age levels tested. In analogies with perceptually separable attributes, change over age was found in sources (d) and (e) noted above. In analogies with perceptually integral attributes, change over age was found in sources (a), (c), (d), and (e). Developmental trends were discussed in terms of past theory and findings, and possible reasons for differences in developmental patterns between the two kinds of analogies were suggested.
