All 126 patterns composed of five dots distributed over the cells of a 3 by 3 matrix were examined for the predictability of their elements. The predictability of a given dot in a given pattern was measured as the percentage of Ss who indicated that dot as one “implied or suggested” by the subpattern composed of the remaining four dots of the pattern. The dots comprising a figurally good five-dot pattern were generally more predictable, one from the others, than the dots comprising a poor pattern. This finding accords with the Gestaltist conception of a good figure as one whose elements are well organized, and it is the state of affairs required by Garner’s hypothesis that better figures are perceived to have fewer alternatives than poorer figures. A mechanism mediating the prediction of an element of a pattern from the other elements was suggested. 相似文献

In order to study infants' sensitivity to binocular information for depth, 11 infants, 20 to 26 weeks of age, were presented with real and stereoscopically projected virtual objects at three distances, and the infants' reaching behavior was videotaped. When the virtual object was positioned out of reach, infants tended to lean further forward and to reach less frequently than when the virtual object was positioned within reach. In addition, the proportion of reaches in which the infants patted, closed their hands, or brought their hands together was greater when the virtual object was within reach. However, no difference in the terminal location of the infants' reaches was found as a function of the virtual object's position. Examination of reaches to a near real object revealed that infants frequently did not contact the object or show appropriate hand shape or orientation. The effectiveness of the cue of retinal size and of binocular information for the depth of an object is discussed. It is concluded that 5-month-old infants are sensitive to binocular information for depth. 相似文献

The initial question was whether subjects could categorize a word semantically before they precisely identified the word itself. This failed to occur. When searching a visual display for a single target word, subjects searched at the same rate whether the distractors were in the same or in a different semantic category. However, when the size of the target set was increased to three, then six, items, subjects increasingly used category information to speed their search rate when targets and distractors belonged to different categories. Subjects appeared to perform the task by comparing the category of each display word to the category of the target set. 相似文献

Tests of proprioceptive shift (PS), visual shift (VS), and negative aftereffect (NA) were made during 25-min exposure to 20-D displacement and during a subsequent 30-min dark decay period in two separate experiments. Different groups of subjects explored hallways or viewed their active hand during exposure. VS was greatest in hall exposure, while PS was greatest in hand exposure. Larger VS occurred in the second experiment, where test procedures were modified to minimize a tendency to center the target within the momentary or remembered field of view. Substantial and possibly complete VS decay occurred when the initial level of adaptation was high, but although PS decay was substantial, it was not complete. In all conditions, the sum of VS and PS numerically exceeded the NA, and this difference tended to be largest and significant in the hall exposure. Implications of this effect for the two-component additivity hypothesis are discussed. 相似文献

Comparaison d'échantillons appariés d'étudiants japonais et américains (niveau lycée et collège universitaire) relativement aux six valeurs que mesure L'inventaire Survey of Personal Values. On a d'abord testé la comparabilité des “valeurs” dans la langue originale de L'inventaire et dans la traduction japonaise: L'analyse factorielle des items traduits et les corrélations calculées entre L'inventaire en japonais et un choix d'échelles japonaises de personnalité donnent des garanties à cet égard. Chez les étudiants japonais des deux sexes et des deux niveaux scolaires, on trouve des moyennes plus faibles pour ce qui est de L'orientation pratique de L'esprit, la réussite et la variété, et des moyennes plus élevées pour L'ordre et L'orientation vers un but. Ainsi, les Japonais accordent moins d'importance aux considérations matérialistes (réussite individuelle, changement ou diversité) mais ils donnent plus de valeur à un mode de vie organisé et routinier et au fait de chercher systématiquement à réaliser des buts bien définis. Les résul-tats de la présente recherche recoupant des recherches antérieures, font apparaître une grande ressemblance entre les deux pays, dans la structure de la personnalité. 相似文献

Preserved learning of novel information in amnesia: Evidence for multiple memory systems 总被引:1,自引:0,他引:1
Barry Gordon 《Brain and cognition》1988,7(3):257-282
Four of five patients with marked global amnesia, and others with new learning impairments, showed normal processing facilitation for novel stimuli (nonwords) and/or for familiar stimuli (words) on a word/nonword (lexical) decision task. The data are interpreted as a reflection of the learning capabilities of in-line neural processing stages with multiple, distinct, informational codes. These in-line learning processes are separate from the recognition/recall memory impaired by amygdalohippocampal/dosomedial thalamic damage, but probably supplement such memory in some tasks in normal individuals. Preserved learning of novel information seems incompatible with explanations of spared learning in amnesia that are based on the episodic/semantic or memory/habit distinctions, but is consistent with the procedural/declarative hypothesis. 相似文献

MMPI and Rorschach indices of schizophrenic and depressive diagnoses among adolescent inpatients 总被引:1,自引:0,他引:1
Although adolescent norms have been developed for the MMPI (e.g., Marks, Seeman, & Haller, 1974) and Rorschach (e.g., Exner, 1986a), little is known regarding the discriminate diagnostic validity of these measures with adolescents. This study investigated the usefulness of these measures in the detection of depression and schizophrenia among adolescent inpatients. Subjects (mean age = 15.3) consisted of 134 adolescents who received Rorschach and MMPI administrations at hospital admission. Clinical diagnoses resulted in the following groupings for this sample: schizophrenia = 15, dysthymic disorder = 41, major depression = 26, conduct disorder = 28, personality disorder = 18. MMPI scale Sc elevation was found to be the most effective single predictor of schizophrenic diagnoses, with a hit rate of .76, sensitivity of .62, and specificity of .78. Neither MMPI scale D scores nor Rorschach DEPI scores were found to be significantly related to patients' diagnoses. Results were interpreted in terms of prior findings in adult psychiatric populations and in relation to implications for the clinical assessment of adolescents. 相似文献

Stimulus-response compatibility in the programming of speech 总被引:2,自引:0,他引:2

Subjects chose between sequences of one syllable (e.g.,/gi/vs./bi/), two syllables (e.g.,/gibi/ vs./gubu/), and three syllables (e.g.,/gibidi/ vs. gubudu/), when/i/sequences were signaled by high-pitched tones and/u] sequences were signaled by low-pitched tones (high compatibility), or the reverse (low compatibility). Choice times were additively affected by sequence length and compatibility. A second experiment showed attenuated compatibility effects for sequences with different vowels in the first and second syllables. These results replicate previously reported results for choices between finger sequences, which suggests that the same programming methods are used in both output domains. Evidently, choices between response sequences can be achieved by selecting a distinguishing parameter and assigning it in a serial fashion to partially prepared motor subprograms. 相似文献
