Beyond the high point code in testing Holland's theory

This study was designed to test and expand Holland's vocational development theory by utilizing more than a single high point code in classification of personality patterns of jobs. Significant positive results were obtained to support Holland's premise that people search out environments and, hence, vocations that are compatible with their personalities. A more “refined” and/or “subtle” difference was shown in the personality-job relationships when two high point codes were used.     

Pressures from work,self, and home in the life stages of married women

Following Lopata's (1966) model of the life cycle of the married woman's role, it was predicted and found that a woman's life stage would be related to her role pressures (work, home, self, and time), conflict, and satisfaction. Age and number of roles were not as strongly related to these variables as was life stage. Work activities and pressures declined through the peak child-rearing stage and then increased for women with older children, while pressures from home generally rose throughout the life cycle. The differential impact of various sources of conflict in different life stages was reported, and forms of organizational career support oriented toward particular life stages were suggested.     

Evaluative and taxonomic encoding in children's memory

The experiments were conducted to investigate the development of evaluative and taxonomic encoding in children's memory. The task used was a modification of the Wickens short-term memory task in which subjects' recall of words is tested following a distraction task. The first experiment found that 11-year-old children, but not 8-year-old children, encoded words using the evaluative dimension of the semantic differential. In the second experiment, both 7- and 11-year-olds demonstrated the ability to encode words according to taxonomic categories. These findings were related to other recent work on the development of encoding in memory.     

Storage and later recognition of exemplars of concepts

This paper concerns the problem of abstraction: whether when we encounter several exemplars of a concept, we retain only the abstracted concept, only the exemplars, or both. Although many studies concur that both are stored, a recent article argued strongly that only the abstracted concept is stored. The present study, aimed at replication of this recent finding, follows the earlier procedural details but adds appropriate controls and uses simpler material. A set of 24 exemplars of four concepts, in the form of four-tuples of letters and numbers, was presented to Ss who, after presentation, rated a larger set of exemplars for recognition. One group of Ss experienced the conceptual exemplars; control group Ss experienced items that were similar in composition but not exemplars of a concept. Two major results appeared: Unlike the study on which this was based, all Ss were able to distinguish those items that were originally experienced from those that were not. And, the more completely an exemplar fit the concept (the longer the item), the more confident the S was that it had been presented. In contrast, in the control condition, the longer the item, the more confident the S was that it had not been presented earlier. Two models are described to account for these results. One is based on the S's initial storage of the exemplars in a concept-plus-correction format; the other is based on a procedure whereby the S can make recognition judgments without having previously abstracted and retained the concepts.     

Facilitation of attention to number and conservation of number

This study examined the relation between number conservation and attention to number, density, and length or area in kindergarteners (age 5 years, 8 months) and third graders (age 8 years, 11 months). Attention was assessed by the dimensional preference technique, using triads. Both the attention and conservation tasks included stimulus factors known to facilitate or hinder conservation: small or large numbers of objects, nonlinear or linear arrays, and trials ordered from easiest to hardest, hardest to easiest, or randomly. The number of objects and type of array affected both tasks similarly and there was an order effect in the attention task. There was an increase in attention to number from kindergarten nonconservers to kindergarten conservers to third-graders. Possible developmental interactions between attention and conservation were suggested.     

Perceptual supports for one-to-one correspondence in the conservation of number

This study compared provoked and spontaneous one-to-one correspondence along with two tasks having more perceptual support for correspondence. These four levels of correspondence appeared in a conservation of number condition and two conservation-related conditions (a partially static array or a static array). There were two sets of stimuli (toy animals or corks) in each condition. In opposition to Piaget's predictions, the four levels of correspondence did not differ in difficulty for kindergarteners. There was a strong order effect (p<.001) in the direction of increasing conservation over the eight trials. There was some evidence that the standard conservation condition was easier than the other two conditions. Implications for Piaget's theory are discussed.     

Suggestibility and type of interpersonal relationship: Special implications for the patient-practitioner relationship

Suggestibility was assessed in five conditions by the subject's response to suggestions falsely labeled as matters of fact. These misrepresentations of fact, or virtual suggestions, denoted a variety of hallucinations, an anesthesia, and an amnesia. They were administered as incidental intrusions while the subject was involved in the primary experimental task. In three of these conditions, the subject either observed his own spontaneous visual imagery, observed visual scenes provided by the experimenter, or simply waited with closed eyes for the presentation of the virtual stimuli. These conditions were characterized by a passive-receptive, interpersonal relationship in which the subject remained silent. Suggestibility was expected to be high. In a fourth condition the subjects described spontaneous visual imagery. This was characterized as an active-receptive relationship in which speech was maintained throughout. The suggestibility of the three passive-receptive conditions was comparable, and none of them differed from a baseline condition involving the formal induction of hypnosis. However, the fourth, active-receptive condition was significantly lower, and this difference survived a replication. Of special interest was the induction of an anesthesia in the majority of subjects in the three passive-receptive conditions.     

Repetition and agreement with opposing arguments: A delayed action effect

If exposure to two arguments supporting opposing conclusions establishes two memory traces that influence attitudes, repetition of one of the arguments should produce a delayed action effect. In a computer-controlled experiment, subjects read a large number of arguments about fictitious brands of consumer products from a T.V. screen. They rated each brand immediately after reading about it and again after spending 10 min reading messages about other brands. In the critical conditions of the experiment, two arguments were presented about each brand. One described a good quality of the product (e.g., excellent durability); the other described a bad quality (e.g., below-average efficiency). Subjects read one of the opposing arguments concerning each brand repeatedly and studied the repeated arguments for memory tests. As predicted, repetition and studying affected ratings on the delayed post-test, but not on the immediate post-test. Specifically, attitudes shifted over the delay toward agreement with the repeated arguments, supporting the idea that the persistence of attitudes depends on more than one memory trace.
