Prepared for anything?: an investigation of female genital arousal in response to rape cues

Men's genital arousal occurs in response to a limited number of sexual stimuli, whereas women's genital arousal occurs in response to a wide range of sexual stimuli, including those depicting nonpreferred cues. Researchers have hypothesized that women's nonspecific pattern of genital arousal prepares the body for sexual activity, thus functioning to protect the genital organs against injury. If this hypothesis is correct, women should show genital responses to any cues suggesting sexual activity, even unappealing cues that involve nonconsensual sex and extreme violence. Fifteen men and 15 women listened to fourteen 2-min audiotaped narratives that depicted an interaction between a man and a woman and that varied factorially according to the presence of consent, violence, and sexual activity. The results support the preparation hypothesis: Men showed the greatest genital arousal in response to narratives depicting consensual, nonviolent sex, whereas women showed similar responses to all the narratives involving sexual activities, including those describing a sexual assault.     

Chunks in expert memory: evidence for the magical number four ... or is it two?

This study aims to test the divergent predictions of the chunking theory (Chase & Simon, 1973) and template theory (Gobet & Simon, 1996a, 2000) with respect to the number of chunks held in visual short-term memory and the size of chunks used by experts. We presented game and random chessboards in both a copy and a recall task. In a within-subject design, the stimuli were displayed using two presentation media: (a) physical board and pieces, as in Chase and Simon's (1973) study; and (b) a computer display, as in Gobet and Simon's (1998) study. Results show that, in most cases, no more than three chunks were replaced in the recall task, as predicted by template theory. In addition, with game positions in the computer condition, chess Masters replaced very large chunks (up to 15 pieces), again in line with template theory. Overall, the results suggest that the original chunking theory overestimated short-term memory capacity and underestimated the size of chunks used, in particular with Masters. They also suggest that Cowan's (2001) proposal that STM holds four chunks may be an overestimate.     

Recognizing one’s own clapping: The role of temporal cues

Do individuals recognize their own clapping? We investigated this question with an off-line paradigm in which the perception of the claps is temporally separated from their generation. In a first experiment, we demonstrated that acoustic recordings of clapping provide sufficient information for discriminating between one’s own performance and that of another participant. Self-recognition was still preserved when the claps were reproduced by uniform tones that only retained their temporal pattern. In a subsequent experiment, we verified that the general tempo provides an important cue for self-recognition. Finally, we showed that self-recognition does not rely on concurrent synchronization of actual movements with the auditory sequences. The results are discussed in the light of current theories about perception-action links.     

Factor structure of the SCL-90-R: is there one?

A review of the literature on the factor structure of the Symptom Check List-90-R (SCL-90-R) and its precursors makes evident the many problems inherent in this clinical assessment tool as a measure of independent dimensions of symptom distress, particularly in psychiatric patients. The many versions of the Symptom Check List are evaluated on several criteria (e.g., factor stability, factor loadings, proportion of variance, etc.). It is concluded that interpreting nine dimensions for clinical purposes is highly questionable. It is perhaps still a better measure of general distress as was intended in its original version approximately three decades ago.     

Switching behaviour as a function of number of options: How much is too much for consumer choice decisions?

The number of alternatives for consumers in almost all purchase situations is increasing at an extremely rapid pace. Although more choices may have many benefits to the consumers, recent studies on choice overload have found that choosing from large alternatives may lead to negative consequences. Majority of the choice overload research has compared only two groups of small versus large assortment size. In extant literature, there is no clarity as to what are small and large assortment sizes. Assortment size used as small in one study has been used as large in some other studies. Small assortment size varied from 2 to 60 choices and large assortment size from 3 to 300 choices in past studies, and the presence of choice overload has been reported at completely different levels of assortment sizes. This study has used an array of six choice sets from 6 to 36 options as compared to just two groups of small versus large assortment. Switching likelihood of consumers was used to capture the choice overload effect in this study. The probability of consumers switching their earlier choice was plotted as a function of number of options using binary logistic regression. Results showed that probability of switching was almost a linearly increasing function of assortment size from 6 to 36 options. The graph of predicted probabilities from 2 to 300 options showed a sharp increase in switching behaviour initially and subsequent flattening of the curve when options became very large.     

What variety of attention is automatically captured by peripheral cues?

Previous studies have shown that the voluntary allocation of attention to a location in space can influence accuracy in two ways. First, additional processing resources can be allocated to the attended location, leading to an improvement in perceptual quality for objects presented at that location. Second, decision processes can be restricted to information arising from the attended location, which improves accuracy without influencing the perceptual representation. The present study examined the operation of these two attentional mechanisms when nonpredictive peripheral cues were used to capture attention automatically. Experiment 1 showed that, like predictive cues, nonpredictive cues influence accuracy by summoning perceptual resources and also by influencing decision processes. However, both the cues and the targets in this experiment were defined by luminance increments, making it possible that the cuing effects were mediated by a task-controlled attentional set rather than being fully automatic. Experiments 2 and 3 examined this possibility by using luminance-defined cues and color-defined targets; evidence was again obtained for both perceptual-level and decision-level attention effects. The capture of attention by a nonpredictive peripheral cue thus appears to influence both perceptual resource allocation and postperceptual decision processes.     

Which limb is it? Responses to vibrotactile stimulation in early infancy

This study focuses on how the body schema develops during the first months of life, by investigating infants’ motor responses to localized vibrotactile stimulation on their limbs. Vibrotactile stimulation was provided by small buzzers that were attached to the infants’ four limbs one at a time. Four age groups were compared cross‐sectionally (3‐, 4‐, 5‐, and 6‐month‐olds). We show that before they actually reach for the buzzer, which, according to previous studies, occurs around 7–8 months of age, infants demonstrate emerging knowledge about their body's configuration by producing specific movement patterns associated with the stimulated body area. At 3 months, infants responded with an increase in general activity when the buzzer was placed on the body, independently of the vibrator's location. Differentiated topographical awareness of the body seemed to appear around 5 months, with specific responses resulting from stimulation of the hands emerging first, followed by the differentiation of movement patterns associated with the stimulation of the feet. Qualitative analyses revealed specific movement types reliably associated with each stimulated location by 6 months of age, possibly preparing infants’ ability to actually reach for the vibrating target. We discuss this result in relation to newborns’ ability to learn specific movement patterns through intersensory contingency.

Statement of contribution

what is already known on infants’ sensorimotor knowledge about their own bodies

• 3‐month‐olds readily learn to produce specific limb movements to obtain a desired effect (movement of a mobile).
• infants detect temporal and spatial correspondences between events involving their own body and visual events.

what the present study adds

• until 4–5 months of age, infants mostly produce general motor responses to localized touch.
• this is because in the present study, infants could not rely on immediate contingent feedback.
• we propose a cephalocaudal developmental trend of topographic differentiation of body areas.

     

Explaining neurocognitive aging: is one factor enough?

As an introduction to the special issue on neurocognitive factors underlying age effects, we discuss a number of recent developments in the literature on aging. The classic distinction between generalized and process-specific cognitive changes with old age has reappeared in the distinctions between the frontal lobe hypothesis and more differentiated views of neurocognitive aging. We argue that neurological decay in the frontal cortex has important implications for cognitive control, but that the frontal lobe hypothesis does not capture the plethora of changes that characterize aging and incorrectly suggests a unitary effect.     

Variations of the cognitive interview: Which one is the most effective in enhancing children's testimonies?

Two experiments were conducted to examine the effectiveness of the combination of instructions used in the Cognitive Interview (CI) and the effectiveness of a new mnemonic, the ‘cued recall’ (CR), on children's recall and suggestibility levels. In the first experiment, 229 children, ages 4–5 and 8–9, participated in a painting session. They were then interviewed with one of six interview protocols: A full CI, four of its variations, or a Structured Interview (SI). The children were then asked some misleading questions. All of the variations of the CI elicited more correct details than the SI, without a concomitant in errors or confabulations. Moreover, the CI with the change order instruction (CO) omitted reduced the children's suggestibility level. In the second experiment, this variation of the CI was tested on 57 children. Results confirmed the effectiveness of this protocol. Copyright © 2009 John Wiley & Sons, Ltd.     

Sentence reading: do we make use of orthographic cues in homophones?

Starting from the finding that currently phonological models of visual word processing predominate, we examined what happened when important morphological information is disclosed in the orthography but not in the phonology. To do so, we made use of a peculiarity in Dutch. In this language, some forms of the present and the past tense of verbs are homophones or homographs. This allowed us to look at the power of orthographic and phonological cues to derive the tense of the verb. Two experiments showed that orthographic cues alone suffice to recover the tense of the verb, and that this recovery does not take more time than tense recovery on the basis of a combination of orthographic and phonological cues. On the basis of these results, we conclude that orthographic cues in homophones are very efficient during silent reading. Our findings, however, do not allow us to conclude whether this is due to a direct route from orthography to meaning, or to a specialised, morpho-syntactic back-up strategy elicited by certain sequences of letters.     

The import of infancy for individual, family, and societal development: commentary on the special section: does infancy matter?

Across their life spans humans actualize a rich potential for cognitive and behavioral plasticity, a set of developmental changes that require regulation of organism-context relations on the part of both the individual and society. An individual’s action on the context must be started in infancy and maintained in subsequent periods of life for adaptive functioning to occur across ontogeny. The process of the individual acting as an agent of his or her own development is continuous, although the particular ways in which such control is manifested will change in developmentally appropriate ways. As demonstrated by the papers in this special issue, the significance of infancy for the rest of the life-span rests on an integration of this continuity and discontinuity within the person-context developmental system.     

Enjoyment of sexualization: is it different for men?

We elucidated the Enjoyment of Sexualization (ES) construct in a sample of 206 female and 118 male undergraduate students. Our male ES Scale had high reliability, and confirmatory factor analyses indicated that a univariate structure was appropriate for both men and women. ES added to the prediction of self‐esteem and number of sexual partners (but not body shame) after controlling for self‐objectification; gender did not moderate these relationships. The relationship between ES and number of sexual partners was moderated by attractiveness such that individuals who believed themselves to be more attractive had more sexual partners at high levels of ES. Furthermore, ES was distinguishable from the conceptually‐related self‐objectification construct with regard to Big Five personality. Finally, results suggested that ES might be less harmful than self‐objectification.     

Comparing Multiple Paths to Mastery: What is Learned?

Contemporary theories of learning postulate one or at most a small number of different learning mechanisms. However, people are capable of mastering a given task through qualitatively different learning paths such as learning by instruction and learning by doing. We hypothesize that the knowledge acquired through such alternative paths differs with respect to the level of abstraction and the balance between declarative and procedural knowledge. In a laboratory experiment we investigated what was learned about patterned letter sequences via either direct instruction in the relevant patterns or practice in solving letter-sequence extrapolation problems. Results showed that both types of learning led to mastery of the target task as measured by accuracy performance. However, behavioral differences emerged in how participants applied their knowledge. Participants given instruction showed more variability in the types of strategies they used to articulate their knowledge as well as longer solution times for generating the action implications of that knowledge as compared to the participants given practice. Results are discussed regarding the implications for transfer, generalization, and procedural application. Learning theories that claim generality should be tested against cross-scenario phenomena, not just parametric variations of a single learning scenario.     

Organization and predictive power of general and relationship-specific attachment models: one for all, and all for one?

Given recent evidence for multiple attachment models, we examined the organization and predictive power of general and relationship-specific attachment representations in two samples using two distinct measures of attachment models. With regard to associations among relationship-specific models, peer models (romantic partner and friend) and parental models (mother and father) were more similar to each other than to any other models, and anxiety/self-model representations were more consistent across relationships than avoidance/other-model representations. With regard to links between general and specific models, romantic and friend models made the strongest and independent contributions to general models, and romantic relationship involvement moderated the importance of romantic models to general models. With regard to differential predictive power of multiple models, general, romantic partner, and mother attachment made unique contributions to well-being indicators; relationship outcomes, however, were only predicted by individuals' corresponding relationship-specific models. Implications for the measurement and conceptualization of adult attachment are discussed.     

Perception of threat cues in post-traumatic stress disorder: Semantic processing without awareness?

Research suggests that anxiety-disordered patients semantically process, without awareness, threat cues occurring in unattended prose passages during dichotic listening (Mathews, 1984). In the present study, we attempted to demonstrate unaware semantic processing of threat cues in Vietnam combat veterans with post-traumatic stress disorder (PTSD). Control Ss included alcoholic and normal veterans, all without combat experience. To provide a rigorous test of the hypothesis, we employed a dichotic listening procedure that strictly controlled the S's attentional resources and prevented momentary attention shifts from producing results spuriously suggesting semantic processing without awareness. The processing measures included skin conductance responses and shadowing errors following presentation of threat words related to Vietnam, phonetically similar words, words threatening for other anxiety-disorder groups and neutral words. The results were inconsistent with the semantic processing without awareness hypothesis, suggesting that previous data adduced as evidence for the phenomenon may have stemmed from prose shadowing procedures that permitted momentary awareness of threat cues on the unattended channel.     

Who is who in dissociation?: A plea for psychodynamics in a time of trauma1

Contemporary theories of dissociation and trauma for the most part have evolved outside of psychoanalysis. Psychoanalytic writings have also been regarded as being in opposition to trauma‐based notions of human psychopathology. The specific psychoanalytic contribution—the emphasis on unconscious conflict and meaning—is for the most part excluded from the discourse on dissociation, often resulting in a mechanic conceptualisation of trauma. In this paper, based on clinical material, the author argues in favour of including conflict, unconscious intention and personal meaning in understanding the kind of dissociation we see in cases of multiple personality pathology. Textual analysis of letters written to the analyst illustrates how events of abuse are defensively elaborated. The author demonstrates that patterns of affect regulation and dominant object–relational strategies can be captured through analysis of the discourse structure. She focuses on how an organised character pattern, revealed mainly through narrative style and the analyst's countertransference, serves protective purposes as well as wishfulfillment. She argues that dissociation in the form of multiple personalities may imply an active, strategic agent.     

Temporary employees in Singapore: what drives them?

In this study the authors provide an empirical analysis of the job attitudes and behavior of temporary workers in Singapore, compiling and categorizing the various reasons individuals choose temporary jobs, in an effort to provide a clear and comprehensive understanding of why people choose this work arrangement. A profile of temporary employees showed that job attitudes are affected by the importance of the various reasons given for being a temporary worker. This exploratory study provides a foundation on which more complex relationships between these variables can be examined.     

Linguistic and cognitive abilities in infancy: when does language become a tool for categorization?

Infants' ability to form new object categories based on either visual or naming information alone was evaluated at two different ages (16 and 20 months) using an object manipulation task. Estimates of productive vocabulary size were also collected. Infants at both ages showed evidence of using visual information to categorize the objects, while only the older ones used naming information. Moreover, there was a correlation between vocabulary size and name-based categorization among the 20-month-olds. The present results establish that infants as young as 20 months can use the non-obvious cue of naming to categorize objects. The possibility of a link between this ability and lexical development is discussed.     

Are number gestures easier than number words for preschoolers?

Some researchers have argued that children's earliest symbols are based on their sensorimotor experience and that arbitrary symbol-referent mapping poses a challenge for them. If so, exposure to iconic symbols (such as one-finger-for-one-object manual gestures) might help children in a difficult domain such as number. We assessed 44 preschoolers’ processing of number gestures and number words on two tasks: give-a-number and how-many. Children were generally more accurate when mapping number words than number gestures onto a number of toys, suggesting that the iconicity of number gestures does not help children map symbols to numbers. We argue that children learn number gestures as arbitrary symbols and do not take advantage of their iconicity.
