Lexical access for concrete and abstract words.

Three experiments with 48 undergraduates compared the speed and accuracy of lexical decisions for concrete and abstract nouns. Results of Exp I, in which separate groups of Ss judged each word type, and of Exp II, in which all Ss judged mixed blocks of both word types, indicate that there was a small speed advantage for concrete nouns in lexical decision. To observe transfer effects from one word type to the other, all Ss in Exp III made judgments within blocked presentations of each word type. Findings show that when blocks of abstract words followed blocks of concrete words, judgments for the abstract words were significantly longer than those for concrete words. When concrete blocks followed abstract blocks, however, there was no difference in response time for the 2 word types. It is concluded that the effect of concreteness in lexical decision appears to be critically sensitive to order of presentation. Implications for models of common vs dual representation in lexical memory are discussed. (56 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Associative learning of abstract and concrete nouns and their subject-drawn pictorial representations.

Conducted 2 experiments to examine undergraduates' associative learning and pictorial representations of 48 concrete and 48 abstract noun pairs. In Exp. I, 24 Ss drew their own pictures of each noun. In Exp. II, another 24 Ss chose S-drawings that best represented their subjective meaning of the word referents. These Ss also received pretraining in labelling the S-drawings. Results from both experiments show that recall of noun pairs was superior to recall of S-drawn picture pairs. These findings conflict with the literature on picture and word paired-associate learning. In addition, concreteness of items facilitated recall. In Exp. I, concrete S-drawings were significantly better retrieval cues than abstract S-drawings. Results are discussed in terms of Pavio's theory of verbal and imagery processes of memory.

Age-related differences in memory as a function of imagery processing.

The effects of aging on imagery production and use (following the learning of concrete and abstract words) and their relations to subsequent memory performance were explored in 2 experiments. Both experiments demonstrated better free recall of concrete than of abstract words (the concreteness effect). Exp 1 showed this superiority to be greater for young Ss only under explicit imagery instructions. Exp 2 revealed that the advantage of concrete over abstract words reflects the use of differential imagery production. The results are discussed in terms of age differences in imagery utilization and the effects of visual processing on recall. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Multicausal inference: Evaluation of evidence in causally complex situations.

Investigated in 2 experiments the types of information that people use in making inferences about causality in uncertain situations in which there are many potentially causal factors. A model previously proposed for unicausal inference by M. W. Schustack and the present 2nd author (see record 1982-02716-001) was found to be appropriate to the multicausal case. In Exp I, 60 abstract causal inference problems were presented to 47 college students. Ss were asked to evaluate the likelihood that the particular set of events described in hypothetical situations would lead to the outcome described. In Exp II, 60 abstract multicausal inference problems were presented to college students, 34 in the abstract condition and 40 in the concrete condition. Findings show that both multicausal and unicausal inference rely primarily on 4 types of evidence concerning the sufficiency and necessity of possible causal events. In multicausal inference, people also consider the representativeness, or resemblance, of the events in a situation to causal models suggested by previous situations. When evaluating multicausal problems presented in either abstract or concrete terms, most people average the unicausal likelihoods of all the events in a situation and adjust for the situation's representativeness. However, when evaluating concrete problems, some people base their multicausal estimates only on the unicausal likelihood for the most likely causal event and the situation's representativeness.

Context and the recallability of concrete and abstract sentences.

Examined the influence of contextual information on the recall of abstract and concrete sentences in 3 experiments, using 216 undergraduates. In Exp I, concrete and abstract target sentences were presented in either a coherent paragraph context or a random paragraph context. In the random context, Ss recalled more concrete target sentences than abstract ones, but there was no difference between the 2 groups when the sentences were presented in a coherent context. Exp II extended this finding by adding a moderately coherent context that used many of the same nouns as the coherent paragraph, but it was not as thematically coherent. Exp II replicated the results of Exp I and found that the moderately coherent context provided intermediate facilitation for the recall of abstract sentences relative to the random context and the coherent context; context structure had no effect on the recall of concrete sentences. In Exp III, the target sentences were abstract and the concreteness of the context was varied. Abstract context sentences were recalled as well as concrete context sentences if the contexts formed a coherent paragraph; if the context was a randomly ordered list of sentences, concrete context sentences were recalled better than abstract context sentences. Results were interpreted in terms of the differential availability of contextual information for abstract and concrete materials and support the context availability model.

Location coding with letters versus unfamiliar, familiar, and labeled letter-like forms.

Errors in reporting a post cued target in a string of several letters more often involve a letter appearing elsewhere in the string (mislocation error) than one not appearing in the string (intrusion error). However, this difference is not found with strings of relatively unfamiliar symbols or forms. Two experiments, with a total of 70 Ss, explored the reason for this difference. Exp 1 showed that the difference was not an artifact of different overall accuracy levels or exposure durations for the 2 character types. In Exp 2, relative to no experience, initial experience with the forms through familiarization or learning labels for them produced mislocation and intrusion frequencies that were more similar to those for letters. This change was related to the development of stored representations for forms that are similar to those for letters.

The effects of rounding on memory for numbers in addition problems.

Recall and recognition of the sums of addition problems were tested using rounded or exact numbers. In Exp 1, 53 Ss were instructed to remember five-digit sums. Recall and recognition were greater for rounded than for exact numbers. In Exp 2, 60 Ss were informed at test to recall only the first two digits. Again, rounded numbers were better remembered. In Exp 3, half of the 72 Ss were informed in advance that they would be tested on only the first two digits. The rounding effect persisted in recognition for these Ss. The advantage for rounded numbers is attributed to less difficult processing requirements which makes more time available for memory processes.

Individual differences in syllogistic reasoning: Deduction rules or mental models?

Conducted 2 experiments to examine the correlates of reasoning ability on a syllogistic reasoning task in Ss who lacked formal background in logic, focusing on the extent to which reasoning proficiency arises from the consideration of multiple possible set relations (mental models) as opposed to explicit or implicit reliance on deduction rules. Exp I investigated whether differences between good and poor reasoners occurred early or late in the process of reasoning. 24 undergraduates, designated as good or poor readers, were presented with 16 syllogisms to solve. In Exp II, 16 good and 15 poor undergraduate reasoners and 7 graduate students who had studied logic were asked to state their initial impression of the correct conclusion to a syllogism. Overall findings reveal evidence for the use of both models and rules. Although good and poor reasoners differed even when time constraints were imposed, consistent with the supposition of a better set of rules among good reasoners, good reasoners showed more improvement and chose to take longer amounts of time when time constraints were removed, suggesting that they considered more alternatives than did the poor reasoners. A comparison between these 2 groups and Ss with experience in logic revealed striking differences in both accuracy and speed.

Note-taking, individual differences, and memory for lecture information.

Investigated the encoding function of note taking and processing differences between successful and less successful students in lecture situations in 2 experiments. In Exp I, 48 undergraduates either took notes or listened during a lecture. Different memory patterns were found for these 2 groups, with note-takers recalling many more high- than low-importance propositions and listeners recalling an equal number of high- and low-importance propositions. Results suggest that note taking enhanced organizational processing of lecture information. In Exp II, the notes and recall of 80 successful and less successful students were compared. Successful Ss recalled more of the most important propositions, but these 2 groups of Ss did not differ in their recall of less important propositions. For both groups of Ss, recall content was closely related to the content of the notes, with successful Ss recording more high-importance propositions in their notes. Also, successful and less successful Ss were similar in their note-taking styles and the degree to which they benefited from reviewing their notes.

Problem-specific information and the development of problem-type schemata.

Examined the proposition that problem-type schemata include both problem-specific and abstract information. Recognition priming was used to capture schema acquisition as it evolves in analogical problem solving. Priming was used to show that Ss form associations in memory between problem-specific sentences drawn from analogous problems. In Exp 1, Ss formed such associations but only when analogical transfer was facilitated. In Exp 2, Ss formed associations only among sentences that related to abstract problem information. In Exp 3, Ss did not form associations among sentences that interfered with access to abstract information during transfer. In Exp 4, Ss accessed problem-specific sentences in problem-type schemata when given new problems of the same type. The results suggest that problem solvers retain problem-specific information in schemata because the information affords access to abstract information during transfer. Results are discussed in terms of a conservative generalization model of schema acquisition that emphasizes the importance of problem-specific information in problem solving.

Teaching with concrete and abstract visual representations: Effects on students' problem solving, problem representations, and learning perceptions.

In 3 experiments, we examined the effects of using concrete and/or abstract visual problem representations during instruction on students' problem-solving practice, near transfer, problem representations, and learning perceptions. In Experiments 1 and 2, novice students learned about electrical circuit analysis with an instructional program that included worked-out and practice problems represented with abstract (Group A), concrete (Group C), or abstract and concrete diagrams (Group AC), whereby the cover stories were abstract in Group A and concrete in Groups C and AC. Experiment 3 added a 4th condition (C-A) with a concrete cover story and abstract diagrams. Group AC outperformed Groups A and C on problem-solving practice in Experiments 1 and 2 and outperformed Group C on transfer across the 3 experiments; Group AC also outperformed Group C-A in Experiment 3. Further, Group A outperformed Group C on transfer in Experiments 2 and 3 and outperformed Group C-A in Experiment 3. Transfer scores were positively associated with the quality of the diagrams and the number of abstract representations drawn during the transfer test. Data on students' learning perceptions suggest that the advantage of Group AC relies on the combined cognitive support of both representations. Our studies indicate that problem solving is fostered when learners experience concrete visual representations that connect to their prior knowledge and are enabled to use abstract visual representations.

Abstract word deficits in aphasia: Evidence from semantic priming.

J.G. and D.E. are nonfluent aphasic patients who appear to have selective problems with abstract words on a variety of standard tests. Such a pattern would normally be interpreted as indicating a central semantic deficit for abstract words. The authors show that this is not the case by means of a semantic priming task that tests for implicit knowledge of the meanings of abstract and concrete words. Spoken word pairs that were either abstract or concrete synonyms (e.g., street-road or luck-chance) were presented; both Ss showed priming for the abstract and concrete pairs. The researchers followed up by asking the Ss to produce definitions to spoken abstract and concrete words; these definitions were also normal. The priming and definition data suggest that the semantic representations of abstract words in these Ss were relatively unimpaired. The researchers found that the Ss have problems only with spoken abstract words in just those tasks where normal controls also have difficulty. In contrast, they clearly have deficits in reading abstract words aloud, which may be due to problems with output phonology. Implications of these data for claims concerning hemispheric differences in the representation of abstract and concrete words are discussed.

Conceptual automaticity in recognition memory: Levels-of-processing effects on familiarity.

Examined the effect of level of processing (LP) on recognition memory using 2 response-signal delays (RSD; 500 and 1500 msec). In Exp 1, LP (semantic or nonsemantic) and RSD were manipulated between 24 college students. In Exp 2, orienting task (pleasantness rating or letter judgment) and RSD were manipulated among 32 Ss. In Exp 3, study orientation and test instructions (inclusion or exclusion) were within-S factors, and RSD was a between-S factor. 32 Ss were included in Exp 3. In Exp 1, a modality effect was found for fast responses. The LP was reliable at both points in time. In Exp 2, fast responses were associated with significantly more "false-alarms" to words encoded semantically than those encoded nonsemantically. In Exp 3, both recollection and familiarity estimates were elevated by prior conceptual processing. Estimates of recollection were affected by RSD.

Increasing the meaningfulness of quantitative material by adapting context to student background.

Conducted 2 experiments to examine the effect of adapting the context of a presentation to a student's background in 2 experiments. In Exp I, 51 preservice teachers studied statistical probability rules presented in 3 contexts. One variation used education-related explanations and examples (adaptive context), another used medical-related (nonadaptive) contexts, and a third used abstract contexts. Posttest results showed the adaptive context to be superior to both of the other contexts on education-related problems and to the abstract context on transfer problems unrelated to education. Little or no advantage was found on standard problems unrelated to education or on memory of formulas. In Exp II, the design was replicated using 50 nursing students as Ss. Results again supported the effectiveness of contextual adaptation, this time showing better performance under medical-related contexts. Learning advantages, however, were more consistent across item types than was the case in Exp I. Findings are interpreted in terms of the effect of adapting context on meaningful learning and motivation. (33 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Risk factors in infant-mother attachment.

In Exp I, 56 preterm Ss born at less than 1,500 g were assessed at 6 wks; at 3, 6, and 9 mo; and at 1 yr for avoidant, secure, and ambivalent attachment patterns. In Exp II, 109 Ss (aged 2–4.5 yrs) with delayed development due to Down's syndrome, diagnosed neurological disorders, and undiagnosed disorders were assessed in a strange-situation setting. In Exp III, 15 Ss with cystic fibrosis and 15 normal Ss (aged 12–18 mo) were assessed for attachment patterns. Data indicate that none of the medical problems had a significant impact on the child–mother relationship. (French abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Internality, controllability, and the effectiveness of attributional interpretations in counseling.

Investigated an attributional approach to counseling in 2 studies. In Exp I, with 58 female and 24 male psychology students, the theoretical basis for the use of attributional interpretations was tested by giving Ss who had just received a negative social evaluation no information or information that stressed 1 of 4 types of causes: internal/controllable, internal/uncontrollable, external/controllable, and external/uncontrollable. Stressing internal/controllable causes produced more positive affective reactions and performance evaluations among internal locus of control respondents (Rotter's Internal–External Locus of Control Scale), whereas externals were more variable in their responses. Exp II (24 Ss) assessed the generalizability of these findings by administering causal counseling to Ss who identified themselves as interpersonally anxious. Utilizing a quasi-counseling design, Ss were exposed to 1 of 2 interpretations emphasizing internal control or coping. Results of Exp II confirm initial conclusions that the effectiveness of causal counseling may depend on the individual's locus of control.

Development of categorical representations for above and below spatial relations in 3- to 7-month-old infants.

A series of experiments examined the abilities of infants to form categorical representations for the spatial relations above and below. Exp 1 provided evidence that 3–4 mo olds can form categorical representations for above and below when a diamond shape was presented above or below a horizontal bar. Exps 2 and 3 showed that 3- and 4-mo olds did not form categorical representations for above and below when a number of discriminably different shapes (e.g., a diamond, a triangle, a dot) appeared above or below the bar. These more abstract categorical representations for above and below were formed by 6- to 7-mo olds (Exp 4). The findings suggest an experientially or maturationally based trend, from concrete to abstract, in the categorical representation of common spatial relations.

Patterns of student growth in reasoning about correlational problems.

Previous studies of correlational reasoning have focused on the interpretation of 2?×?2 tables. The research in this article examined age trends in responses to problems involving more than 2 continuous variables. Instruments were developed and administered to Ss from Grade 4 through postgraduate (n?=?20 in each grade) to produce multidimensional profiles of student growth. Exp 1 found that correlational reasoning skills increased with age. Exps 2 and 3 found that student performance could be improved through instruction. Evidence of convergent and discriminant validity of the instruments was obtained. Although there were similarities between results obtained with 2?×?2 data problems and results on continuous data problems, the evidence in support of a single correlational schema underlying both was ambiguous. There was no transfer, and correlations between the 2 types of performance were weak. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Hypnosis, task-motivating instructions, and learning performance.

40 Ss, including 30 who had been previously rated as suggestible and 10 as nonsuggestible, were pretested and then retested on equivalent forms of 3 learning tasks: digit symbol substitution, memory for words, and abstract reasoning. All Ss received the pretests in the same way. The 30 suggestible Ss were retested under 1 of the following 3 experimental treatments with 10 Ss assigned at random to each treatment: task-motivating instructions, hypnotic induction procedure with task-motivating instructions, and control. The 10 nonsuggestible Ss were retested under a task-motivating-instructions treatment. Analyses of covariance indicated that (a) task-motivating instructions given alone or following a hypnotic induction procedure did not significantly affect performance on the memory for words or abstract reasoning tasks; and (b) task-motivating instructions produced a comparable enhancement of performance on the digit symbol substitution task in hypnotized and nonhypnotized Ss and in suggestible and nonsuggestible Ss.
