Developmental constraints associated with children's use of the keyword method of foreign language vocabulary learning

Second- and sixth-grade (ages 7 and 11 years, respectively) subjects were instructed to learn simple Spanish vocabulary nouns using the keyword method. To remember a foreign word translation the keyword method user must: (1) associate the foreign word to an English word (the keyword) that sounds like part of the foreign word; and (2) remember an image of the keyword and translation referents interacting. Second-grade keyword users who were provided with interactive pictures remembered more vocabulary items than those who generated their own imagery links when given separate pictures of the keyword and translation referents. Second graders who generated their own linking images when given only the keywords and translation words recalled fewer items than both picture groups, and were not significantly different from control subjects. Sixth graders in the three imagery-link variations performed at comparable levels and better than control subjects. The results are in complete accord with previous speculations about the development of imagery strategies in children.     

Sexual arousal and interpersonal evaluations

In an attempt to reconcile conflicting results concerning the effects of sexual arousal on interpersonal evaluations, hypotheses based on adaptation level, arousal-need gratification, and labeling of arousal explanations were tested. The variables of sexual arousal, technique of stimulus material presentation, physical attractiveness of the original stimulus female, and physical attractiveness of the final target person being judged were manipulated in a 2 × 2 × 2 × 2 design. A significant three-way interaction (Arousal × Stimulus Attractiveness × Target Attractiveness) obtained on all measures of interpersonal evaluation was interpreted as supporting a labeling of arousal explanation. It is suggested that subjects first interpret their arousal as being caused by their attraction toward the stimulus person. The characteristics of the stimulus person then become a factor used by subjects when they subsequently make judgments of target females. The adaptation-level and arousal-need gratification hypotheses were not supported.     

Incorporating inferences in narrative representations: A study of how and why

Four experiments examined the conceptual organization of narrative passages and the extent to which these representations were explanatory in a variety of experimental tasks. The conceptual representation of a passage consisted of a graph of labeled nodes and labeled, directed arcs which were adopted from the Conceptual Dependency Theory. These representations included both explicitly stated information and inferences which had been empirically extracted by a question-answering procedure. Symbolic procedures for answering how- and why-questions were also delineated. The conceptual representations and the symbolic procedures that operate on these representations together accounted for 91% of the answers generated from question-answering protocols in Experiment 1, and also the rated quality of specific answers to specific questions in Experiment 2. Experiments 3 and 4 supported the hypothesis that structural properties of the representations can predict recall of explicitly stated nodes and verification ratings of inference nodes. The results provide encouraging support for the proposed graphic representations and also for the use of question-answering protocols in uncovering prose inferences.     

The naive perception of masculinity-femininity on the basis of expressive cues

Groups of naive judges rated 18 videotaped stimulus persons on masculinity, femininity, “dominance, assertiveness,” and “compassion, sensitivity to others.” Stimulus persons were broken down by sex and sex-typing—half were male, half female—and within sexes one third were classified as masculine, feminine, and androgynous on the basis of their scores on the Bem Sex Role Inventory. Two experiments are reported in which groups of judges rate stimulus persons on the basis of such different expressive information as videotaped pictures and recorded voices, videotaped pictures alone, videotaped bodies, videotaped heads, recorded voices, and still photos. The results showed: (1) Judges reliably rated masculinity-femininity from largely expressive cues: (2) judgments of masculinity-femininity were not predominantly determined by judgments of sex role-related traits: (3) the naive judgment of masculinity-femininity significantly corresponded to stimulus subjects' assessed sex roles; (4) stimulus subjects (particulary males) showed a consistent display of masculinity-femininity across expressive channels; and (5) judges used different expressive cues in judging masculinity-femininity in males and females. These results are related to broader questions concerning the relation between expressive behavior and personality.     

Stochastic transitivity and the unidimensional control of choice

A concurrent-chains paradigm was used to test three models of preference for schedules of reinforcement. Each model assumes choice to be a monotonic function of values on a single dimension (“simple scalability”). For choices involving variable-interval and fixed-interval schedules, this dimension is assumed to be an harmonic average of the interreinforcement intervals; for choices involving fixedinterval and fixed-ratio schedules, the dimension is the time to reinforcement irrespective of response rate; for choices involving different combinations of rate and duration of reinforcement, the dimension is the rate of “reinforcement-time”, or the product of the two parameters. Each model implies a strong form of transitivity (“functional equivalence”), which held for half the subjects (that half exclusively sensitive to the reinforcement variable specified by the model). An alternative unidimensional model which implies a weaker form of transitivity (“weak binary utility model”) was consistent with the preferences of all subjects. This model states that a single factor controls the direction of preferences but not necessarily the exact choice probability, as simple scalability assumes.     

Beauty and the attributions of the beholder

Four studies used an attributional approach to examine interpersonal attraction. Underlying causal dimensions were predicted to influence differentially two components of attraction, dating and complimenting. In the first study, 24 subjects indicated whether they would date physically attractive stimulus persons. Complimenting was examined in the second and third studies, with 24 subjects rating the likelihood of complimenting attractive opposite-sex stimulus persons and 32 subjects rating the likelihood of complimenting same-sex stimulus persons. For these studies the reason for the stimulus person's attractiveness varied in controllability (volitional versus nonvolitional) and stability (temporary versus permanent). Consistent with predictions, controllability influenced likelihood of complimenting but not dating. In addition, compliments were more likely when the reason for attractiveness was unstable than when stable. Conversely, dating was more likely when attactiveness was stable than when unstable. However, stability had less influence on men responding to women than on either men responding to men or women responding to both sexes. Similar results were obtained in a fourth study in which 56 subjects recalled incidents where they complimented or dated others for their physical attractiveness.     

The development of the category-recall relationship in the sorting-recall task

The relationship between categorical organization and recall for children in grades two, four, and six (ages 8, 10 and 12 years, respectively), and for adults was investigated using the sorting-recall procedure. Subjects sorted unrelated words on individual cards into either two, four, or six categories prior to output, and recall performance improved significantly as a function of increased numbers of sorting categories. The category-recall relationship was shown to be independent of the effects of subject-determined item exposure time in sorting. This result was taken as evidence for a basic structural property of memory (“chunking”) that does not vary as a function of age. We further speculated that the slopes of the category-recall function obtained in this study suggest a limit on the size of organizational units in young children's memory.     

A component model for diagnosing and treating children who stutter

Nine components of stuttering and their distribution among 54 children who stutter are described. The components are arranged into a model that includes four neurologic components (attending disorder, auditory-processing disorder, sentence-formulation disorder, and oral-motor disorder) and five traditional components (high self-expectations, manipulative stuttering, disruptive communication environment, unrealistic parental expectations, and abnormal parental need for the child to stutter). Diagnostic and treatment usefulness of the model are discussed. Thirty-two of the children have been followed through component-based treatment and 12 mo post termination. Results indicate that treatment was successful with 27 (84%) of the 32 children. Only one child regressed during the 12 mo after treatment ended. These results suggest that treating the neurologic and traditional factors which disrupt fluency improves maintenance and carry-over.
