Imagery and verbal associative latencies as a function of imagery ability.

Examines RTs of Ss high or low in imagery ability under instructions to elicit a verbal associate or arouse an image to concrete and abstract noun stimuli. 16 high and 14 low imagers were selected from a sample of 77 volunteer undergraduates. Latencies were significantly shorter for high than low imagers, for concrete than abstract words, and for verbal than imagery instructions. 1 interaction showed that imagery latencies were shorter to concrete than to abstract stimuli, whereas the latencies of verbal associations did not differ for the 2 types of words; another revealed that the relative superiority of high over low imagers in reaction speed was greater when the stimuli were abstract. Correlational data suggest that verbal associations may be mediated by both verbal and imaginal processes, thus favoring high imagers in both instruction conditions, and that self-reports of imagery ability can reliably predict imaginal behavior.

The associative interference hypothesis in verbal discrimination transfer: Reply to Paul.

Acknowledges the validity of the criticisms of H. Paul (see record 1979-02840-001) regarding the failure to specify the mechanism(s) whereby incidental associative interference produces a negative effect on discrimination learning in certain verbal discrimination transfer paradigms. Such hypothesized mechanisms are discussed, and alternative explanations based on interference from incidentally learned contextual associations are proposed.

A test of the developmental imagery hypothesis in children's associative learning.

Two samples of kindergartners (a total of 125 Ss) were administered a paired-associate learning task at the beginning and end of the school year, under either regular (control) or self-generated visual imagery instructions. Consistent with previous speculations about the relationship between maturation and the efficacy of imagery instructions on this task, age predicted paired-associate learning performance in the imagery condition even when general ability and amount of formal schooling were controlled. In contrast, age was not significantly related to learning in the control condition. Results support the developmental imagery hypothesis.

Acquired equivalence and distinctiveness in human discrimination learning: Evidence for associative mediation.

In the first stage of Experiments 1-3, subjects learned to associate different geometrical figures with colors or with verbal labels. Performance in Stage 2, in which the figures signaled which of 2 motor responses should be performed, was superior in subjects required to make the same response to figures that had shared the same Stage 1 associate. A third stage of testing showed that the events used as associates in Stage 1 were capable of evoking the motor response trained in Stage 2, an outcome predicted by an associative interpretation of such transfer effects. Experiment 4 provided evidence that the relevant associations can be effective in controlling motor responding even when subjects report an antagonistic relationship between the events.

The associative interference hypothesis in verbal discrimination transfer: A note on the Eckert and Kanak review.

E. Eckert and N. Kanak (see record 1975-02303-001) suggested that in addition to the frequency theory, the hypothesis of associative interference is necessary to explain the negative transfer observed in the discussed verbal discrimination transfer paradigm. The present note suggests that the associative interference inferred in this paradigm is a correlate of the negative transfer but does not specify the mechanism needed to explain such transfer.

Age differences in incidental learning.

Examined the effects of age and of incidental-learning tasks on recall of a categorized word list. Ss were 50 18-30 yr old college students and 50 55-65 yr old teachers. The control groups were instructed to remember the words; incidental-learning groups performed orienting tasks, but were not informed that they would have to recall the words. 2 orienting tasks required that Ss process the meaning of the words; the other 2 orienting tasks did not involve semantic processing. Analysis of the free-recall data indicates that the semantic processing tasks led to much greater recall and organization of recall than the nonsemantic orienting tasks. In recall, there was a significant interaction between age and orienting task, with old Ss only manifesting incidental learning that was inferior to young Ss, whose orienting task involved semantic processing. The findings indicate that the presence or absence of an age-related decrement in incidental learning is predictable from the depth of processing of the incidentally acquired material.

Verbalization effects in discrimination learning of pictures and words.

Compared discrimination learning of pairs of pictures (line drawings) and their verbal labels as a function of various verbalization conditions in a study with 128 undergraduates. Ss either (a) verbalized each item of a pair once (condition C1) or twice (condition C2), (b) verbalized the right item 3 times and the wrong item once (condition R), or (c) verbalized the right item once and the wrong item 3 times (condition W). The R and W conditions affected discrimination learning of both pictures and words in a way predictable from frequency theory, but pictures were easier to discriminate than words in conditions C1, R, and W. It is suggested that the results reflect the joint operation of verbal frequency and visual encoding processes in picture discrimination. (French summary) (17 ref.)

Hypnosis and verbal learning.

Rigidly standardized hypnotic procedures were used in a double-blind experiment which examined the acquisition ability of Ss who differed in hypnotic susceptibility for the learning of both meaningful (poems) and meaningless (nonsense syllables) material when hypnotized and when unhypnotized. Regression analyses indicated that: (a) Differences in relative degree of hypnotic susceptibility among Ss did not influence the learning of nonsense syllables or poems; (b) S's degree of manifest anxiety and verbal intelligence did not contribute significantly to performance scores; and most important, (c) the application of hypnosis did not significantly influence performance on either nonsense syllables or poems when compared to performance in the unhypnotized treatment.

Anxiety and verbal learning.

3 groups, differing in anxiety, learned 2 different types of paired-associate materials and then half of each anxiety group were tested under "immediate" and half under "delay" conditions of intertrial spacing. The first 2 groups were college students selected from extreme scorers on the Taylor Manifest Anxiety Scale and the third group was composed of hospitalized anxious patients. "Among the students, the high and low groups, tested under both delay and immediate conditions, showed no significant differences in their learning of the word-associate material. With the more novel and difficult false equations, however, the high anxiety Ss learned significantly less over all and showed a somewhat slower rate of learning from trial to trial. Among the patients, those tested under the delay condition performed about as well as the high-anxiety students, while those under the immediate condition learned a lesser amount both of the word and equation materials." 19 references.

Age differences in verbal learning.

"An old and a young group of Ss, mean ages 78.1 and 26.8 years, were given 3 paired-associate learning tasks which differed in the degree to which prior experience might be expected to facilitate or block present learning. They consisted of: (a) Familiar word pairs, (b) nonsense equations, and (c) false equations. Both groups performed best on the word-associate task, but there was little difference between the learning of nonsense and false equations within either group. On all 3 procedures the old group was significantly poorer, but they were proportionately more deficient in the learning of materials in which the facilitative effects of prior experience are minimized, i.e., the 2 forms of equations. However, they had no greater difficulty with the interference than with the nonsense material." 16 references. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Projective methods and verbal learning.

"This experiment investigated the question of whether some methods of measuring verbal learning were more sensitive than others in revealing the effects of frequency and consequence. It was found that the effects of frequency were homologous, regardless of the test used to measure verbal learning. The methods were not equivalent in revealing the effects of consequence (reward and punishment). The more difficult the particular test used to measure verbal learning, the lower was S's absolute score and the more likely to appear were the effects of reward and punishment."

The Minnesota conference on associative processes in verbal behavior.

The Committee on Linguistics and Psychology of the Social Science Research Council held a work conference at the University of Minnesota on April 25-26, 1955, "to facilitate communication among a small group of research workers who were interested in problems of verbal association." "The program consisted of seven discussion sessions and a summary session." Papers were presented by W. A. Russell, J. J. Jenkins, W. A. Bousfield, L. J. Postman, C. N. Cofer, D. H. Howes, S. Saporta. Titles of the papers are given and a summary statement concerning each is given. Similarities and differences, types of objectives emphasized, and methodological trends are discussed. "With reference to differences in conceptualization, the participants seemed to be divided with respect to practically all dimensions."

The effects of anxiety level and psychological stress on verbal learning.

"It was predicted that under neutral conditions high anxiety (high drive) Ss would exhibit a performance superior to that of low anxiety (low drive) Ss on a paired-associate learning task with minimal intratask interference but that under conditions of psychological stress (report of inadequate prior performance) high anxiety Ss, due to the greater arousal of interfering extratask responses, would no longer exhibit the superiority found under neutral conditions. Results indicated that while the high anxiety Ss under neutral instructions were significantly superior to the low anxious, as predicted, and the Ss operating under stress were inferior to their neutral controls, the predicted interaction between anxiety level and stress was not found."

The effects of concurrent verbal and visual tasks on category learning.

Current theories of category learning posit separate verbal and nonverbal learning systems. Past research suggests that the verbal system relies on verbal working memory and executive functioning and learns rule-defined categories; the nonverbal system does not rely on verbal working memory and learns non-rule-defined categories (E. M. Waldron & F. G. Ashby, 2001; D. Zeithamova & W. T. Maddox, 2006). However, relatively little research has explored the importance of visual working memory or visual processing for either system. The authors investigated the role of working memory (Experiment 1a and 1b), visual processing (Experiment 2), and executive functioning for each system, using a concurrent task methodology. It was found that visual tasks with high executive functioning demands and verbal tasks with high or low executive demands disrupted rule-defined learning, whereas any visual task, regardless of executive functioning demand, disrupted non-rule-defined learning. Taken together, these results confirm the importance of verbal working memory and executive functioning for the verbal system and provide new evidence for the importance of visual processing for the nonverbal system. These results help to clarify understanding of the nonverbal system and have implications for multiple systems theories of category learning (F. G. Ashby, L. A. Alfonso-Reese, A. U. Turken, & E. M. Waldron, 1998). (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Configural processes in human associative learning.

The extent to which human discrimination learning is based on elemental or configural stimulus representations was examined in 7 experiments. In Experiments 1a and 1b, participants were able to learn nonlinear discrimination problems in a food-allergy task. In unique-cue theories, such learning is explained by individual stimulus elements acquiring independent connections with the outcome and also combining to form unique cues that function elementally. In Stage 1 of Experiments 2, 3, and 4a–c, Food A signaled an allergy outcome (O) (A?→?O) when presented alone but signaled no allergy (AB?→?no O) when paired with Food B. In Stage 2, Food B was paired with the allergy (B?→?0). In a test phase, the original discrimination between A and AB was found to be intact, at variance with the unique-cue theory. By contrast, in Experiments 5a, 5b, and 6, an effect of the B?→?O trials on the A–AB discrimination was observed with training procedures previously found by D. A. Williams (1995) to encourage elemental processing. Experiment 7 showed that the influence of B?→?0 trials on the A–AB discrimination was unaffected by pretreatments designed to foster an elemental processing strategy.… (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The differential functions of imagery and verbal thought in insomnia.

Individuals with insomnia were exposed to a stressor (speech threat) prior to getting into bed and were instructed to think about the speech and its implications in either images (Image group, n = 14) or verbal thought (Verbal group, n = 17). Participants completed questionnaires about speech anxiety, arousal, and sense of resolution. Measures were taken of subjective (sleep diary estimates) and objective (actigraphy) sleep-onset latency. In the short term, the Image group reported more distress and arousal relative to those in the Verbal group. In the longer term, the Image group estimated that they fell asleep more quickly and, the following morning, reported less anxiety and more comfort about giving the speech compared with the Verbal group.

Observation and discrimination learning in the rat: Specific and nonspecific effects.

After watching the performance of a model rat (N = 10), 48 Os (naive male hooded rats) were trained on a visual pattern discrimination. Results show that the observational experience facilitated discrimination learning if the same cue pattern was positive for the model and the O; it retarded learning in Ss trained on the reversal of the observed discrimination. These results depend on the viewing of a model contiguous with the cue pattern. A 2nd type of facilitating effect followed visual exposure to the cue patterns presented without a model S. When such an observational condition involved stimulus change, discrimination learning was facilitated regardless of the cue to be approached.

Feature-positive discrimination learning.

In Experiments 1, 2, and 3, pigeons were trained with an ABC+ BCo discrimination, in which three stimuli, A, B, and C, were presented together and paired with food, and the compound BC was followed by nothing; they were also trained with a DEF+ Eo Fo discrimination in which stimuli E and F were presented separately and followed by nothing, whereas the compound DEF was paired with food. On completion of discrimination training, test trials with the feature A consistently revealed a higher rate of responding than with D. In Experiment 4, reinforced presentations of D were intermixed with the DEF+ Eo Fo discrimination. Test trials revealed that E enhanced responding when it was paired with F, but it had the opposite effect when paired with D. The results are seen as being more consistent with a configural than an elemental model of conditioning. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
