Perception of less irregular and more irregular stimuli.

Berlyne's stimuli were presented in a stereoscope to test his hypothesis that Ss prefer the more irregular member of a pair of stimuli. 32 Ss, screened for normal acuity and phorias, were tested. Contrary to Berlyne's hypothesis and consistent with earlier stereoscopic studies, Ss tend to report more frequently the less irregular member of a pair of stimuli. These data can be explained by an information-conflict model; however, the clearest implication of this study was that experiments concerned with familiarity of stimuli should be qualified by the method.     

Structuralism and experimental aesthetics: Bridging some gaps

Structuralism in psychology has much to do with what Berlyne called his rival tradition in aesthetics, the speculative and interpretative approach. Berlyne's concern with motivation can be retained while structuralism's emphasis on understanding is accepted.This paper was originally presented at the Berlyne Symposium, American Psychological Association Meeting, San Francisco, August 1977.

Children's preference for complexity as a function of perceived units in collative motivation

The purpose of this investigation was to manipulate a constant number of four elements (red and blue rectangles) to represent differentially perceived units of complexity. The hypothesis that motivational arousal and choice preferences of second- and fifth-grade children would be a positive function of the number of perceived units, ranging from one to four, was confirmed, consistent with Berlyne's (1960) theory. When the number of elements was held constant at three, as compared to four, similar results were obtained in a test at two intermediate levels of complexity. Implications for organization of elements and the effects of symmetry in determining children's preferences for levels of complexity are discussed.     

Berlyne's theoretical contributions to psychology

The evolutions of Berlyne's theoretical contributions are traced by contrasting his particular developments with seven characteristics of Hullian theory. Berlyne is seen to have dismantled each element and replaced it with a vastly different theoretical position and structure. Berlyne developed a truly general theory, which was then differentiated with special concepts in specific areas as diverse as thinking and aesthetics.Much of the content of this article first appeared in Walker (1961).     

Mere repeated exposure and experimental stress as determiners of stimulus evaluations

From Berlyne's theorizing concerning the determinants of hedonic value of a stimulus it was hypothesized that importance of evaluative judgments and frequency of exposure would interact in determining the favorability of affective ratings. This prediction was confirmed by the data. Increasing the importance of the rating task decreased the favorability of the ratings of low-frequency stimuli but enhanced the ratings of high-frequency stimuli.The experiments reported here were conducted at the Laboratorium voor Experimentele Sociale Psychologie at Leuven. This article is based on the author's doctoral dissertation, which was supervised by J. M. Nuttin, Jr. I would also like to thank J. M. Nuttin, Jr., E. Van Avermaet, and J. Hatcher for their helpful comments on a previous draft.     

The new experimental aesthetics—The beginning or the end?

In reference to recent work in aesthetics from a scientific perspective, Berlyne coined the phrase the new experimental aesthetics. Berlyne's contributions to this research area are discussed in terms of the philosophical, theoretical, and methodological issues central to the current literature. The paper concludes with a consideration of the future prospects for experimental aesthetics.This paper was presented at a symposium in honor of Daniel E. Berlyne at the annual meeting of the American Psychological Association, San Francisco, August 27, 1977. The presentation of this paper was supported by a grant from York University.     

Verbal responses of male college students to human figure paintings varying in collative properties, perceived sexuality, and perceived aggression

20 male undergraduates rated 60 human figure paintings on verbal scales to index collative variability (e.g., simple-complex), perceived sexuality, and perceived aggression in the stimuli. Regression equations were used to predict epistemic (interest) and diversive (pleasingness) responses to the paintings. Collative variability predicted diversive but not epistemic appreciation. Perceived aggression was the strongest predictor for both types of aesthetic reaction. Perceived sexuality was most strongly related to diversive appreciation. Both linear and nonlinear functions emerged and these were discussed in terms of consistency with Berlyne's 1971 theory of aesthetics.     

Reactions to uncertainty: A comparison of three motivational theories

This study attempted to explicate some of the variables underlying preference, pleasure, and reward. In order to accomplish this, Jones's (1966, 1969) information drive theory, Berlyne's (1967, 1971, 1973, 1978) optimal arousal potential theory, Helson's (1964, 1966, 1971, 1973) adaptation-level theory, and McClelland and Clark's (1953) discrepancy hypothesis were experimentally contrasted. Subjects (316) rated the hedonic tone, perceived uncertainty, arousing properties, and interest value of two series of visual stimuli of specified uncertainty. Regression analyses revealed that immediately prior experience with stimuli varying in uncertainty affected rating of perceived uncertainty and arousing properties but had no major effects on ratings of hedonic tone and interest value. The results did not support Jones's and McClelland and Clark's models. Berlyne's model seemed to account for the affective hedonic tone and interest results, while Helson's model best explained the nonaffective perceived uncertainty and arousal data. It was concluded that nonaffective variables are affected by short-term experience with uncertainty while affective variables are not. Speculations concerning the phenomenon of interest value were then offered.Jewish Child Care AssociationThis article is based on a dissertation submitted to the New School for Social Research in partial fulfillment of the Ph.D. requirements.

The latent structure of trait curiosity: evidence for interest and deprivation curiosity dimensions

To evaluate Litman and Jimerson's (2004) Interest/Deprivation (I/D) model of curiosity, 355 students (269 women, 86 men) responded to 6 trait curiosity measures including the Curiosity/Interest in the World scale (C/IW; Peterson & Seligman, 2004), the Curiosity and Exploration Inventory (CEI; Kashdan, Rose, & Fincham, 2004), the Perceptual Curiosity scale (PC; Collins, Litman, & Spielberger, 2004), the Epistemic Curiosity scale (EC; Litman & Spielberger, 2003), and the Curiosity as a Feeling-of-Deprivation scales (CFD; Litman & Jimerson, 2004). Consistent with expectations, the results of confirmatory factor analyses demonstrated that the C/IW, CEI, PC, EC scales defined an Interest (I) curiosity factor, whereas the CFD scales formed a Deprivation (D) curiosity factor. However, as compared to the other interest-based curiosity measures, one of the EC subscales was found to be less differentiated from the CFD scales, presumably because these instruments assess overlapping aspects of Berlyne's (1954) concept of epistemic curiosity. The results of this study indicated that I and D curiosity are related but differentiated curiosity dimensions, providing evidence for the validity of the I/D model.     

Exploration,arousal and autism

Summary From Berlyne's theory of exploration three predictions were derived concerning exploratory behaviour of autistic children. These predictions related to (a) the latency and level of exploratory responsiveness, (b) the modulation of the internal state and (c) the temporal course of exploration.To test these predictions, subjects were exposed to a completely novel object in an otherwise familiar environment, and again on five subsequent occasions.The results showed a remarkably consistent trend in exploration over all subjects: although initially inhibited and depressed, exploration eventually increased to a level comparable with that of normal subjects of the same age. But this responsiveness also showed a relatively rapid decline. Thus exploration of novelty was a parabolic function of time. The original predictions received substantial but not entire support.The results were discussed in terms of the interaction between collative and organismal variables, as novelty and arousal.     

Children's attention to stimulus components with variation in relative salience of components and degree of stimulus integration

A total of 400 children at ages 5, 9, and 12 years were given a component selection task with stimuli differing in color and shape. Relative salience of these two stimulus components was manipulated across subjects in two ways: the standard shapes and colors from previous studies were compared with standard shapes in fluorescent colors, and the latter materials were compared with nonsense shapes in fluorescent colors. While fluorescence of color had little effect, the replacement of standard shapes with nonsense figures caused attention to be redirected from shape to color as the primary cue for learning. This effect was more pronounced at age 9 than at age 5. Apparently there is a greater tendency for older than for younger children to withdraw attention from a normally dominant component such as shape, when it is advantageous to adopt another feature such as color as the primary functional cue. An additional variable was integration of components (color within shape vs color as background for shape). Integration produced generally greater attention to color but did not affect the general pattern of salience effects.     

Resting Heart Rate,Vagal Tone,and Reactive and Proactive Aggression in Chinese Children

Abundant research conducted in Western contexts has shown that biological risk factors such as low resting heart rate (HR) might be related to childhood aggression. However, it was unclear (1) how resting HR, as well as other markers of cardiac functions such as resting vagal tone, may be related to subtypes of aggression such as reactive and proactive aggression, and (2) whether the HR-aggression relation can be replicated in non-Western contexts. Therefore, this study examined the concurrent and prospective relations between resting HR, vagal tone, and Chinese children’s reactive and proactive aggression. Participants were 183 children (M age?=?7.64 years, 91 girls) recruited from an elementary school in Zhenjiang, PRC. Children’s resting HR and vagal tone were assessed in the second grade (T1). Teachers rated children’s reactive and proactive aggression in the second (T1) and fourth grade (T2). Results showed that lower resting HR at T1 was associated with higher reactive and proactive aggression at T1 and T2, and higher vagal tone was associated with lower HR, which in turn was related to higher reactive and proactive aggression at T1 and T2. Lower vagal tone was directly related to higher reactive but not proactive aggression at T1 and T2, whereas lower HR was related to higher reactive aggression at T2 for children with low or moderate vagal tone but was not for children with high vagal tone. These psychophysiological findings from a non-Western context add additional support for both similarities and differences between reactive and proactive aggression in childhood.     

Physical Environmental Adversity and the Protective Role of Maternal Monitoring in Relation to Early Child Conduct Problems

Research on the development of externalizing behaviors during early childhood has focused on child and parenting factors. Fewer studies have investigated effects of aversive features of the micro-level physical environment, such as overcrowding and chaos in the home, and the macro-level environment, such as neighborhood quality. This study extends research on physical environmental factors by examining their association with children's early externalizing behaviors, and exploring how maternal monitoring may serve as a protective factor in such contexts. 120 male toddlers at high risk for developing early externalizing behaviors were followed from ages 2 to 5 years. Direct longitudinal associations were found for micro-level environmental factors beginning at age 2 and for neighborhood risk beginning at age 3. Maternal monitoring served as a protective factor for child externalizing behaviors in the context of neighborhood risk. Implications for prevention research and the development of early externalizing behaviors are discussed.     

Maternal depression and parental distress among families in the Early Head Start Research and Evaluation Project: Risk factors within the family setting

This study examined the influence of risk factors within the family environment (inadequate resources, insufficient caregiving support from child's father, higher family conflict) on maternal well being (depression and parental distress) using a longitudinal panel research design. Participants consisted of 2,040 low‐income mothers of young children enrolled in the Early Head Start (EHS) Research and Evaluation Project. Findings indicated that greater family resources at 14 months had a protective effect on maternal well‐being at 36 months, controlling for demographic variables and maternal well‐being at 14 months. Furthermore, the effect of family resources on maternal well‐being was moderated by father caregiving support, such that family resources were protective, particularly when father caregiving support was lower. Family conflict at 14 months was associated with lower maternal well‐being at 36 months, controlling for demographic variables and maternal well‐being at 14 months. Our findings suggest that low‐income mothers need the support and resources of programs such as EHS to overcome the hurdles and challenges of parenting in high‐risk settings. Implications for clinical practice and EHS are discussed.     

An inexpensive and automated method for presenting olfactory or tactile stimuli to rats in a two-choice discrimination task

An inexpensive and automated method for presentation of olfactory or tactile stimuli in a two-choice task for rats was implemented with the use of a computer-controlled bidirectional motor. The motor rotated a disk that presented two stimuli of different texture for tactile discrimination, or different odor for olfactory discrimination. Because the solid olfactory stimuli were placed outside the chamber in metal pods with a mesh at front for odor sampling, "washout" of odors between trials was not necessary. To avoid differential auditory cues from motor rotation, the stimuli were arranged such that on each trial the motor always rotated exactly one quarter revolution (in 1 s), left or right, to present the next stimulus at trial start. To illustrate the use of the equipment, 2 rats were trained on tactile discrimination and 2 rats on olfactory discrimination. The rats sampled the stimulus on the disk through a port on the back wall by sniffing at it (olfactory) or touching it (tactile). The task was a go-left/go-right discrimination with the stimulus on the disk being discriminative for which lever provided reinforcement. The rats reached a stable level above 90% correct after 21 and 32 training sessions for tactile and olfactory discrimination, respectively. The article outlines how the equipment was constructed from low-cost components. Inputs from and outputs to the equipment were implemented through the parallel port of a personal computer without the use of a commercial interface board. The method of automated and low-cost presentation of olfactory or tactile stimuli should be of use for a variety of experimental situations such as matching-to-sample and cross-modal discrimination.     

White guilt and racial compensation: the benefits and limits of self-focus

In two studies, the authors investigated guilt as a response to group-based advantage. Consistent with its conceptualization as a self-focused emotion, White guilt was based in self-focused beliefs in racial inequality. Thus, guilt was associated with belief in White privilege (Study 1) and resulted from seeing European Americans as perpetrators of racial discrimination (Study 2). Just as personal guilt is associated with efforts at restitution, White guilt was predictive of support for affirmative action programs aimed at compensating African Americans. White guilt was not, however, predictive of support for noncompensatory efforts at promoting equality, such as affirmative action programs that increase opportunities (Study 2). In contrast, the other-focused emotion of group-based sympathy was a more general predictor of support for different affirmative action policies. Our findings demonstrate the benefits and limits of group-based guilt as a basis of support for social equality and highlight the value of understanding the specific emotions elicited in intergroup contexts.     

Roles and Representations of Women in Early Chinese Philosophy: A Survey

An understanding of the roles and representations of women in classical Chinese philosophy is here derived from central texts such as the Analects, the Lienü Zhuan, and the I Ching. We argue that the roles of women during the classical period of Chinese philosophy tended to be as part of the “inner,” working domestically as a housewife and mother. This will be shown from three passages from the Analects. Women were represented as submissive and passive, as with the qualities ascribed to yin energy, and therefore as rightfully subordinate to men. However, despite representations of women in philosophy being thus at this time, there were exceptions, specific women who could take a male “outer” political role. The story of Jing Jiang from the Lienü Zhuan suggests that although women being involved in “outer” affairs were looked down on, there were still women who would be and who would occasionally get praised for doing so. This shows that it was realized, explicitly or otherwise, that women were capable of taking those roles, but also that they were not allowed to take such roles at that time.     

Perceptual awareness and its loss in unilateral neglect and extinction

We review recent evidence from studies of patients with unilateral neglect and/or extinction, who suffer from a loss of awareness for stimuli towards the affected side of space. We contrast their deficit with the effects of damage to primary sensory areas, noting that such areas can remain structurally intact in neglect, with lesions typically centred on the right inferior parietal lobe. In keeping with preservation of initial sensory pathways, many recent studies have shown that considerable residual processing can still take place for neglected or extinguished stimuli, yet without reaching the patient's awareness. This ranges from preserved visual grouping processes through to activation of identity, semantics and emotional significance. Similarly to 'preattentive' processing in normals, such residual processing can modulate what will enter the patient's awareness. Recent studies have used measures such as ERPs and fMRI to determine the neural correlates of conscious versus unconscious perception in the patients, which in turn can be related to the anatomy of their lesions. We relate the patient findings to neurophysiological data from areas in the monkey parietal lobe, which indicate that these serve as cross-modal and sensorimotor interfaces highlighting currently relevant locations as targets for intentional action. We speculate on the special role such brain regions may play in perceptual awareness, seeking to explain how damage to a system which appears primarily to code space could eliminate awareness even for non-spatial stimulus properties at affected locations. This may relate to the extreme nature of 'winner-takes-all' functions within the parietal lobe, and their correspondingly strong influence on other brain areas.
