Toward A Very Idea Of Representation

The actual approaches of Cognitive Science offer a partial explanation of cognition. In this paper, our main point is to catch some key elements from these approaches, that can be taken together in a future perspective for a better explanation of cognition. The key elements (levels of analysis, primitives, processes, structures, threshold,self-organisation, bidirectionality, emergency, habituation, tasks, theinteraction between levels and also the interactions between the elements of the cognitive system and the environment) help us to stress the need of the representations. Then, we arediscussing the following dichotomies: procedural-declarative,consciousness-unconsciousness, implicit-explicit. Finally, we will try to motivate the necessity of an abstract theory of representation in Cognitive Science. ``The sensitive things aren't, but the ideas are'.Plato     

Modeling cognitive load effects of conversation between a passenger and driver

Cognitive load from secondary tasks is a source of distraction causing injuries and fatalities on the roadway. The Detection Response Task (DRT) is an international standard for assessing cognitive load on drivers’ attention that can be performed as a secondary task with little to no measurable effect on the primary driving task. We investigated whether decrements in DRT performance were related to the rate of information processing, levels of response caution, or the non-decision processing of drivers. We had pairs of participants take part in the DRT while performing a simulated driving task, manipulated cognitive load via the conversation between driver and passenger, and observed associated slowing in DRT response time. Fits of the single-bound diffusion model indicated that slowing was mediated by an increase in response caution. We propose the novel hypothesis that, rather than the DRT’s sensitivity to cognitive load being a direct result of a loss of information processing capacity to other tasks, it is an indirect result of a general tendency to be more cautious when making responses in more demanding situations.     

The contribution of role satisfaction,meaning in life and work–home conflict to explaining well-being among working grandparents

Background and objectives: The study aimed to examine the relationship of satisfaction with occupied roles as well as the sense of meaning in life and experience of work–home conflict to well-being among working grandparents in Israel.

Design and methods: The research sample consisted of 316 employed grandparents aged 50–80 (153 grandfathers and 163 grandmothers), who were employed in various types of organizations. Data were collected using structured questionnaires. Structural equation modeling was used for data analysis.

Results: The research findings indicate that the sense of meaning in life mediated the relationship between role satisfaction and the two types of work–home conflict. A significant relationship was found between “work interferes with family” conflict and negative affect. Higher personal resources were associated with higher meaning in life. Gender was not related to the experience of work–home conflict or to any of the outcome variables.

Conclusions: The centrality of meaning in life in the model that explains the experience of work–home conflict and its outcomes among working grandparents, derives from its mediating role in the relationship between the experience of role satisfaction and both types of role conflict, as well as from its direct impact on positive and negative affect.     

Concordance among readers of self-help books about important ideas

Amount of agreement among readers about the relevant information in a self-help psychology book was measured to assess whether readers' choices are unique or overlapping. 15 men and 14 women attended two 1-hr. sessions in which they read and marked relevant information in the first 60 pages of a self-help psychology book. Comparison of the amount and pattern of marking across pages and lines on five specific pages showed that there was a statistically significant amount of agreement on which pages contained relevant ideas and which lines contained important concepts. There were no differences between men and women.     

Task interference from event-based intentions

Task interference occurs in prospective memory tasks when an intention deleteriously affects performance on an ongoing activity in some way. Several studies have shown that task interference can manifest itself in slower latencies to perform an ongoing task. Recent evidence demonstrates that associating intentions to certain performance contexts affects prospective memory performance (see, e.g., Cook, Marsh, & Hicks, 2005). In the present study, an intention was associated with a particular stimulus class, such as pictures or words. We found that task interference could be reduced when participants could reliably predict that the material about to be processed was irrelevant to the intention. This material-specific interference effect was found on a trial-by-trial basis in a random sequence of two different kinds of materials across two experiments and with blocking manipulation in another experiment. These results demonstrate that task interference is not a monolithic construct; rather, it results from dynamic and flexible attentional allocation strategies that can change on a trial-by-trial basis.     

Walking through doorways causes forgetting: Situation models and experienced space

We investigated the ability of people to retrieve information about objects as they moved through rooms in a virtual space. People were probed withobject names that were either associated withthe person (i.e., carried) or dissociated from the person (i.e., just set down). Also, people either did or did not shift spatial regions (i.e., go to a new room). Information about objects was less accessible when the objects were dissociated from the person. Furthermore, information about an object was also less available when there was a spatial shift. However, the spatial shift had a larger effect on memory for the currently associated object. These data are interpreted as being more supportive of a situation model explanation, following on work using narratives and film. Simpler memory-based accounts that do not take into account the context in which a person is embedded cannot adequately account for the results.     

Family secrecy: a comparative study of juvenile sex offenders and youth with conduct disorders

The reported research was designed to compare adjudicated male juvenile sexual offenders and youth with conduct disorders on five aspects of family secrecy and deception. Twenty-nine male juvenile sex offenders and 32 comparison youth from three child welfare agencies in New York State participated in the study. Research assistants, blind to the hypotheses of the study and status of the youth, coded agency records for five variables identified a priori as a basis of comparison. Analyses revealed that the two groups were different on three of the five and on the total number of items scored. Families of juvenile sex offenders told more lies, had more family myths, and were more likely to be involved in taboo behavior. Logistic regression revealed that this factor of family deception significantly increased the odds of sexual offending over and above other measures of family pathology. These data support the hypotheses of the study and have implications for both clinical practice and future research in this area.     

On rejecting emotional lures created by phonological neighborhood activation

The authors conducted 2 experiments to assess how phonologically related lures are rejected in a false memory paradigm. Some phonological lures were emotional (i.e., taboo) words, and others were not. The authors manipulated the presence of taboo items on the study list and reduced the ability to use controlled rejection strategies by dividing attention and forcing a short response deadline. The results converge on the idea that participants reduce false alarms to emotional lures by setting more stringent recognition criteria for these items based on their expected memorability. Additionally, emotional lures are less familiar than nonemotional lures because emotional lures have affective and semantic features that mismatch studied nonemotional items.     

Detecting event-based prospective memory cues occurring within and outside the focus of attention

Event-based prospective memory cues are environmental stimuli that are associated with a previously established intention to perform an activity. Such cues traditionally have been placed in materials that receive focal attention during an ongoing activity. This article reports a direct comparison of event-based cues that occurred either within the focus of attention or at the periphery of such attention. When the cue occurred outside focal attention, manipulating that cue changed event-based prospective memory. The identical manipulation had no effect on event-based responding if the cue occurred within focal attention. These results suggest that cue characteristics can compensate for attention being directed away from an aspect of an ongoing task that contains event-based prospective memory.     

Coping with stereotype threat: denial as an impression management strategy

Four experiments tested the hypothesis that people who are concerned with impression management cope with stereotype threat through denial. Consistent with this hypothesis, temporary employees threatened by a stereotype of incompetence (Study 1) and hostel-dwelling older adults (Study 2) were more likely to deny incompetence if they were high in impression management. African Americans (Study 3) showed a similar pattern of denying cognitive incompetence, which emerged primarily when they were interviewed by a White experimenter and had attended a predominantly Black high school. In Study 4, White students who expected to take an IQ test and were threatened by a stereotype of being less intelligent than Asians were more likely to deny that intelligence is important if they were high in impression management.
