The importance of cue familiarity and cue distinctiveness in prospective memory

Abstract

Both retrospective cued-memory tasks and event-based prospective memory tasks require that cue and target information be associated, and that aspects of that association be reinstated for successful remembering. These functional similarities between retrospective memory and prospective memory were the bases for the hypothesis that the familiarity and the distinctiveness of the target event (cue) would influence prospective memory performance. Experiment 1, focusing on target familiarity, found a nominal advantage in prospective memory with unfamiliar target events. Experiment 2 showed a significant benefit for unfamiliar target events, as well as for target events that were distinctive relative to the local context. Additionally, prospective memory performance did not reliably correlate with explicit retrospective memory tasks (recall and recognition), but did correlate with an indirect retrospective memory task (word fragment completion). This pattern suggests and helps specify the general view that prospective memory processes may be similar to those involved in both direct and indirect tests of retrospective memory.     

Evidence for a detrimental relationship between hypertension history, prospective memory, and prefrontal cortex white matter in cognitively normal older adults

Hypertension affects many older adults and is associated with impaired neural and cognitive functioning. We investigated whether a history of hypertension was associated with impairments to prospective memory, which refers to the ability to remember to perform delayed intentions, such as remembering to take medication. Thirty-two cognitively normal older adult participants with or without a history of hypertension (self-reported) performed two laboratory prospective memory tasks, one that relied more strongly on executive control (nonfocal prospective memory) and one that relied more strongly on spontaneous memory retrieval processes (focal prospective memory). We observed hypertension-related impairments for nonfocal, but not focal, prospective memory. To complement our behavioral approach, we conducted a retrospective analysis of available structural magnetic resonance imaging data. Lower white matter volume estimates in the anterior prefrontal cortex were associated with lower nonfocal prospective memory and with a history of hypertension. A history of hypertension may be associated with worsened executive control and lower prefrontal white matter volume. The translational implication is that individuals who must remember to take antihypertensive medications and to monitor their blood pressure at home may be impaired in the executive control process that helps to support these prospective memory behaviors.     

Prospective memory and aging: preserved spontaneous retrieval,but impaired deactivation,in older adults

Prospective remembering is partially supported by cue-driven spontaneous retrieval processes. We investigated spontaneous retrieval processes in younger and older adults by presenting prospective memory target cues during a lexical decision task following instructions that the prospective memory task was finished. Spontaneous retrieval was inferred from slowed lexical decision responses to target cues (i.e., intention interference). When the intention was finished, younger adults efficiently deactivated their intention, but the older adults continued to retrieve their intentions. Levels of inhibitory functioning were negatively associated with intention interference in the older adult group, but not in the younger adult group. These results indicate that normal aging might not compromise spontaneous retrieval processes but that the ability to deactivate completed intentions is impaired.     

ALL ANIMALS MATTER: MARC BEKOFF'S CONTRIBUTION TO CONSTRUCTIVE CHRISTIAN THEOLOGY

Abstract. Along with Jane Goodall, Mark Bekoff proposes that religion can join science in recognizing that animals have minds of their own; that humans can humbly imagine themselves inside these minds, all the while recognizing their independent integrity; and that, as creatures with psyches, animals deserve respect and care. In his various writings Bekoff offers many hints of what a theology of animal minds might look like and how it might be part of a more comprehensive theology of respect and care for the community of life. Process or Whiteheadian theology offers a way of appreciating Bekoff's insights, linking them with the ecojustice movement, showing how they can be linked with various themes in evolutionary biology, and developing a threefold approach to animal well‐being: cosmological, ethical, and spiritual. In so doing, process thought shows how the practice of science, particularly as expressed in cognitive theology, involves a marriage of empathy and observation, which represents science and spirituality at their best.     

Preposition-phrase attachment in noun phrases

This paper examines the ambiguity of noun phrases (NPs) with postmodifying preposition phrases (PPs), such as the triangle next to the circle below the square. This ambiguity is attributable in part to the difference in attachment sites for the second PP. If it attaches low, it modifies just the NP that is the object of the first preposition, and the resulting structure is right branching. If it attaches high, it modifies the entire preceding NP, and the resulting structure is left branching. However, each of these structures itself has two distinct interpretations. In the case of the high-attachment structure, these different interpretations have been previously noted; we call them stacking and coordinating. In the stacking interpretation, each PP modifies the entire NP to its left, whereas in the coordinating interpretation, it modifies just the head noun to its left (the first noun in the construction). In the case of the low-attachment structure, only the interpretation corresponding to the coordinating one has been noted; we call it alternating. However, a fourth distinct interpretation is possible, which corresponds to the stacking interpretation of the highattachment structure; we call it stuffing. In the alternating interpretation, each preposition has scope only over the head of the NP that is its complement. In the stuffing interpretation, each preposition has scope over its entire complement. In a pilot study, we found that the interpretations based on low attachment are preferred to those based on high attachment by a 21 ratio. Of the two low-attachment interpretations, alternating is preferred to stuffing by a 201 ratio. However, of the two high-attachment interpretations, coordinating is preferred to stacking by only a 21 ratio. In a second pilot study, we examined the pattern of interpretations of phrases with four PP postmodifiers of an NP, which in principle have 112 distinct interpretation types. Eleven of these types were noted in the experimental materials. We provide a detailed analysis of these types and note that the relative preference of the various interpretations found in the first study is preserved.     

The child as informant: Eliciting linguistic intuitions from young children

In this paper we report an interview technique we have developed to elicit judgments from young children about the well-formedness and referential properties of sentences. Judgments are compared with act-out responses of a group of 20 children ranging in age from 3 years 9 months to 5 years 4 months. We argue that judgment data are more revealing of children's grammars than are traditional performance tasks.     

Predicting employee theft: A quantitative review of the validity of a standardized measure of dishonesty

One tool used in the preemployment setting for the prediction of theft is thePersonnel Selection Inventory (PSI) (London House, 1980). The PSI is a paper and pencil measure containing three scales: honesty, violence/emotional instability, and drugs. This paper focussed on the usefulness of the PSI dishonesty scale in the prediction of employee theft. Criterion-related validity data from 1,806 persons across 23 samples were quantitatively summarized. All samples met predetermined decision rules. The data indicated that the validity of the PSI dishonesty scale was dependent on a severity of consequences moderator. Validity coefficients are highest when the subject's responses are anonymous, when the theft criteria are self-report measures, when the subjects are students, and when the subjects are aware that the investigator has another source of information on their honesty. In all analyses, the validity of the PSI scale was found to be in useful ranges and showed little variance across studies.The opinions expressed in the report are those of the authors, and do not necessarily represent those of any organizations with which the authors are associated.

Distinctiveness effects in recall:

Unusual information is generally recalled better than common information (the distinctiveness effect). Differential processing accounts propose that the effect occurs because unusual material elicits encoding processes that are different from those elicited by common material, and strong versions of these accounts predict distinctiveness effects in between-list as well as within-list designs. Experiment 1 employed a between-list design and manipulated presentation rate. Contrary to differential processing predictions, no distinctiveness effect emerged, nor did recall patterns for atypical versus common sentences differ as a function of presentation rate. Experiment 2 further tested differential processing accounts as well as representation accounts via a within-list manipulation and conditions that included experimenter-provided elaborations. Distinctiveness effects emerged in all conditions and, contrary to differential processing predictions, the pattern of recall in the elaborated conditions did not differ from that in the unelaborated conditions. Taken together, the results of this study lend more support to a representation view that suggests mechanisms related to the representation and subsequent retrievability of elements in the memory record play a major role in the distinctiveness effect.     

Pictorial enhancement of text memory: Limitations imposed by picture type and comprehension skill

We examined the kinds of information in a prose passage that is better remembered when depictive illustrations are embedded in the passage than when the passage contains no illustrations. Experiment 1 showed that (1) pictures depicting details effectively increased recall of those details and (2) pictures depicting relationships effectively increased recall of that relational information (relative to a no-picture control condition). In Experiment 2, comprehension skill was found to modulate the general effects obtained in Experiment 1. Detail pictures enhanced the recall of targeted details for all skill levels. Relational pictures enhanced recall of pictured relational information for highly skilled and moderately skilled comprehenders, but not for less skilled comprehenders. Because there were no recall differences across the different skill levels in the no-picture control condition, it is suggested that pictures may serve to enable processing in which readers would not necessarily engage under ordinary circumstances. Pictures, however, did not appear to compensate for limitations reflected in lower scores on a standardized test of reading comprehension.
