Centrality preferences in choices among similar options

Three explanations were explored for the finding that people prefer the middle option rather than the extremes when choosing from an array of similar options. In Study 1, 68% chose the middle item from a set of three highlighters and three surveys, whereas 32% chose an item from either end, p < .0001. In Study 2, 71% selected the middle chair from a row of three chairs that were either all empty, or had a backpack occupying either one of the two end chairs, p < .0001. These results support a minimal mental effort principle rather than a preference for symmetry rule. In Study 3, 54.2% recalled more graphic items from the center poster of a 3-poster collage, whereas 31.3% and 14.5% recalled more items from the left and right posters, respectively, p < .004. These findings lend additional support to a focus of attention explanation.     

Positive and negative affect,depression, and cognitive processes in the Cognition in the Study of Tamoxifen and Raloxifene (Co-STAR) Trial

ABSTRACT

Objectives: This study examined the relationship between positive and negative affect, depressive symptoms, and cognitive performance. Methods: The sample consisted of 1479 non-demented, postmenopausal women (mean age = 67 years) at increased risk of breast cancer enrolled in the National Surgical Adjuvant Breast and Bowel Project’s Study of Tamoxifen and Raloxifene. At each annual visit, women completed a standardized neuropsychological battery and self-report measures of affect and depression. Data from three visits were used in linear mixed models for repeated measures using likelihood ratio tests. Separate analyses were performed to relate positive/negative affect and depression to each cognitive measure. Results: Higher positive affect was associated with better letter fluency (p = .006) and category fluency (p < .0001). Higher negative affect was associated with worse global cognitive function (p < .0001), verbal memory (CVLT List B; p = .002), and spatial ability (p < .0001). Depressive symptoms were negatively associated with verbal knowledge (p = .004), figural memory (p < .0001), and verbal memory (p’s ≤ .0001). Discussion: Findings are consistent with some prior research demonstrating a link between positive affect and increased verbal fluency and between depressive symptoms and decreased memory. The most novel finding shows that negative affect is related to decreased global cognition and visuospatial ability. Overall, this research in a large, longitudinal sample supports the notion that positive affect is related to increases and negative affect to decreases in performance on distinct cognitive measures.     

Modeling recall memory for emotional objects in Alzheimer's disease

ABSTRACT

Objective: To examine whether emotional memory (EM) of objects with self-reference in Alzheimer's disease (AD) can be modeled with binomial logistic regression in a free recall and an object recognition test to predict EM enhancement.?Method: Twenty patients with AD and twenty healthy controls were studied. Six objects (three presented as gifts) were shown to each participant. Ten minutes later, a free recall and a recognition test were applied. The recognition test had target–objects mixed with six similar distracter objects. Participants were asked to name any object in the recall test and identify each object in the recognition test as known or unknown.?Results: The total of gift objects recalled in AD patients (41.6%) was larger than neutral objects (13.3%) and a significant EM recall effect for gifts was found (Wilcoxon: p < .003). EM was not found for recognition in AD patients due to a ceiling effect. Healthy older adults scored overall higher in recall and recognition but showed no EM enhancement due to a ceiling effect. A logistic regression showed that likelihood of emotional recall memory can be modeled as a function of MMSE score (p < .014) and object status (p < .0001) as gift or non-gift.?Conclusion: Recall memory was enhanced in AD patients for emotional objects indicating that EM in mild to moderate AD although impaired can be provoked with strong emotional load. The logistic regression model suggests that EM declines with the progression of AD rather than disrupts and may be a useful tool for evaluating magnitude of emotional load.     

The learning ability paradox in adult metamemory research: Where are the metamemory differences between good and poor learners?

College students’ ability to judge whether a studied item had been learned well enough to be recalled on a later test was examined in three experiments with self-paced learning procedures. Generally, these learners compensated for item difficulty when allocating study time, studying hard items longer than easy items, but they still recalled more easy items than hard items and tended to drop items out too soon. When provided with test opportunities during study or a delay between study and judgment, learners compensated significantly more for item difficulty and recalled substantially more. Paradoxically, good and poor learners compensated similarly for item difficulty and benefited similarly from testing during study and from delayed decision making. Thus, although the ability to make metamemory decisions was shown to be important for effective learning, these decisions were made equally well by good and poor associative learners. An analysis of tasks used to investigate metamemory-memory relationships in adult learning may provide an account for this apparent learning ability paradox.     

Word frequency effects in immediate serial recall: Item familiarity and item co‐occurrence have the same effect

In immediate serial recall, high‐frequency words are better recalled than low‐frequency words. A prevalent interpretation of this effect suggests that, at the point of recall, degraded representations undergo a reconstruction process calling upon long‐term knowledge of the to‐be‐remembered items. Recently, Stuart and Hulme () following Deese (), suggested that high‐frequency items are better recalled due to their better long‐term associative links. Their results revealed that a familiarisation procedure involving repeated presentations of the to‐be‐remembered items in pairs abolished the usual frequency effect. In the experiment reported here, an alternative interpretation of this result is examined. Prior to the memory task, subjects received either no familiarisation, item familiarisation, or pair familiarisation. Both item and pair familiarisation improved the item recall of low‐frequency items to the same extent, suggesting that increased familiarity can account for the co‐occurrence effect.     

Costs and benefits of dropout schedules of test–restudy practice: Implications for student learning

Almost all previous studies examining the benefits of testing for promoting student learning have used fixed schedules of practice. However, students more often report utilizing a dropout schedule of practice, in which items are dropped from practice once they are known. Two experiments investigated the costs and benefits of utilizing a dropout schedule of test–restudy practice. Participants learned Swahili–English paired associates using a dropout schedule or a fixed schedule. In the dropout schedule, items received test–restudy practice until each item was correctly recalled once. In the fixed schedule, all items received three tests–restudy practice trials regardless of whether they were correctly recalled, as in previous research. Experiment 2 also included a second learning session. In both experiments, a final cued recall test was administered several days later. Results indicated that the benefits of the dropout schedule (fewer practice trials used overall and all items correctly recalled once during practice) need to be considered in light of the costs (lower levels of final test performance).

Metamemory and reality monitoring

Metamemory judgements and reality monitoring judgements were compared for real and imagined stimuli. Line drawings of everyday items were either perceived or imagined in differing ratios, to (a) investigate people's ability to predict the class of item that would be better recalled (Judgements of Learning, JOL), and the class of item which would be better sourced (Judgements of Source, JOS) in a future recall test, and (b) test the hypothesis that participants would show a bias towards calling remembered items real when the source had been forgotten. Although participants' JOLs indicated that they believed real items would be more memorable than imagined, in both experiments a larger proportion of items from either class (real or imagined) was only recalled when presentation modality was less frequent for that class. By contrast, JOSs were no different for real or imagined items, even though source attribution was more accurate for real than imagined items. An attribution of memories to real rather than to imagined events that often occurs when participants are unsure about the source (labelled a ‘bias towards the real’) was due to phenomenological qualities of the memories. The results are discussed in terms of Johnson and Raye's ( 1981 ) reality‐monitoring model. Copyright © 2002 John Wiley & Sons, Ltd.     

On the relative and absolute strength of a memory trace

Subjects studied either an 8- or 16-word list and later recalled the items while a voice key recorded each response latency. The trials were partitioned by recall total in order to examine the means and distributions of both latencies and interresponse times as a function of recall total. Each analysis was consistent with the view that an item’s absolute strength determineswhether it is recalled whereas an item’s relative strength determineswhen it is recalled. In addition, mean latency was effectively proportional to study list length yet independent of recall total. All of the analyses were consistent with the view that the set of study items is sampled according to a relative-strength rule until all items are found and that a sampled item is recovered into consciousness only when its absolute strength exceeds a fixed threshold.     

Effect of two methods of introducing foods during feeding treatment on acceptance of previously rejected items

The effects of using a single food item (e.g. bread) versus using multiple items (e.g. bread, pasta, and rice) when establishing food acceptance via an escape prevention procedure were investigated with six children who presented with food selectivity. Eating was exposed to a differential reinforcement of food acceptance treatment package but food acceptance did not improve. Criterion levels of appropriate eating (> 80% acceptance, < 20% expulsion, and < 20% disruption) were subsequently established with either nonremoval of the spoon or physical guidance for each of the participants. Three of the children were presented with only one food item during acquisition of acceptance. The other children were presented with three different food items from the same food group. It was found that acquisition of acceptance was more rapid for the single‐item group but that food acceptance was more likely to generalize to previously rejected items for the multi‐item group. The implications for clinical intervention are discussed. Copyright © 2002 John Wiley & Sons, Ltd.     

Free recall and retrieval speed of categorized items by kindergarten children

Kindergarten Ss were presented with 16 pictorial items in four category sets or a partially random ordem with one item from each category composing the four presentation sets. The pictures were presented either on conceptually related background pictures or on white backgrounds. The categorically grouped presentation facilitated free recall performance, both in terms of number of items recalled and the speed with which the items were recalled, and increased the amount of clustering in recall. Categorical clustering in recall was associated with shorter within- than between-category intervals and for those Ss who recalled items from each of four categories successively, the over-all temporal pattern in recall closely approximated that found with adults. No background effects were found.     

Psychophysiological correlates of organizational change and threat of unemployment among police inspectors

The study examined psychosocial work-conditions and physiological reactions among thirty-six police inspectors (median age 45 years, 81% males) who participated in a reorganization. At this time, subjects were threatened by unemployment and had to reapply for their positions in a new police district. Data were collected during the reorganization and at three years follow-up, by means of questionnaires (Stress Profile) and blood samples. The blood samples were used to determine serum levels of gammaglutamyltransferase (GGT), glucose, lipids, prolactin, testosterone and cortisol. The results show a positive association betweenworry about employment and symptoms ofburnout during the reorganization. Mean scores for the Stress Profile sub-scalesworry about employment (p<.01) andwork-load (p<.05) decreased between measurements but an impairment inrelationships with management was noticed (p<.05). No significant changes were observed in terms of self-rated health complaints. Significant decreases in total cholesterol (p<.0001), LDL-cholesterol (p<.0001), LDL/HDL-ratio (p<.01), prolactin (p<.0001), as well as increases in testosterone (p<.01) and cortisol (p<.001) were observed for the whole sample. Glucose decreased with marginal significance (<.07). Controlling for age and gender, multivariate regression analyses showed that subjects who reported deteriorations insatisfaction with work manifested the most modest decreases in prolactin (p<.05). Also, the decrease in glucose was larger for subjects who experienced impairments in,satisfaction with work (p<.05), information (p<.05), task-oriented leadership, (p<.05), andrespect and dignity (p<.05). Subjects who perceived deteriorations in theethical and moral standards of the organization increased their cortisol level to a lower degree than their counterparts (p<.05). Favorable changes in employment status and psychosocial work environment seem to be related to improved physiological functioning.     

The effect of being in a tip-of-the-tongue state on subsequent items

The tip-of-the-tongue state (TOT) is the feeling that an inaccessible item will be recalled. In the TOT induction paradigm, participants are given a list of general information questions or word definitions, and the participants indicate whether they are in a TOT for each item. The present study explored the effect that being in a TOT for one item (N) has on the recall and the likelihood of a TOT for the subsequent item (N + 1). Three experiments were conducted. All three experiments showed that TOTs do not affect the rate of recall for the next item but decrease the likelihood of a TOT for the next item. This effect extended to items occurring two items after the initial TOT (N + 2) in two experiments. Thus, TOTs are less likely to occur after another TOT than after an item not in a TOT. These data are interpreted within a metacognitive framework.     

Religiosity and Marital Satisfaction

This study examined the association between religiosity and marital satisfaction among first-married and remarried adults. Seven hundred and eighty-seven heterosexually married adults from the Flanders region in Belgium completed the Maudsley Marital Questionnaire (MMQ) and a four-item religiosity scale, measuring marital satisfaction and religiosity respectively. This study found the effect of gender and marital status statistically significant (p < .0001) on religiosity. For marital satisfaction, the effect of gender and marital status statistically significant only for MMQ-S (p < .0001) and MMQ-M (p < .0001) respectively. Religiosity had a significant positive correlation (r = .19, p < .0001) with sexual-adjustment problems (MMQ-S). The ultimate aim of this study was to inform marital and relational therapists the value of a possible association religiosity has on marital satisfaction.This study was conducted at the Institute for the Family and Sexuality Sciences, Katholieke Universiteit Leuven, as part of doctoral research.     

Measuring a macho personality constellation

A Hypermasculinity Inventory was developed to measure a macho personality constellation consisting of three components: (a) calloused sex attitudes toward women, (b) violence as manly, and (c) danger as exciting. The 30 forced-choice items were selected by a two-stage internal consistency item analysis. Issues of substantive and structural validity were addressed by considering item content, test format, homogeneity of items, and the factor structure of items. The Cronbach α coefficient for the Hypermasculinity Inventory was .89 in the present sample of 135 college men. External validity was assessed by correlating scores of the Hypermasculinity Inventory with self-reported drug use, r(135) = .26, p < .01, aggressive behavior r(135) = .65, p < .001, and dangerous driving, r(136) = .47, p < .001, following alcohol consumption, and delinquent behavior during the high school years, r(135) = .38, p < .01. Construct validity was supported further by a pattern of theoretically meaningful correlations with the Personality Research Form (D. N. Jackson, 1974, Goshen, NY: Research Psychologists Press). The discussion considered further research that is needed to adduce additional evidence for the construct validity of the Hypermasculinity Inventory as a measure of the macho personality pattern.     

Procedural justice effects on self-esteem under certainty versus uncertainty emotions

Building upon the idea that procedural justice effects are more pronounced when uncertainty is high, we proposed that recall of an uncertainty-eliciting emotion (fear) will render people more responsive to variations in procedural justice than will recall of a certainty-eliciting emotion (disgust). Results from Study 1, (n = 79 undergraduate students) confirmed that a fair procedure (voice condition) enhanced self-esteem relative to an unfair procedure (no voice condition) to a greater extent when people recalled fear than when they recalled disgust. Results from Study 2 (n = 147 undergraduate students) also showed that a fair, relative to an unfair, procedure enhanced self-esteem more strongly when recalling the emotion of fear rather than disgust, but only when these emotions were recalled from a self-immersed than a self-distanced perspective. These findings confirm that discrete emotions that orient people to interpret situations in uncertain versus certain ways are important antecedents of procedural justice effects.     

Association of Burnout with Emotional Coping Strategies,Friendship, and Institutional Support Among Internal Medicine Physicians

Physician burnout influences physician mental health, staff stress, safety events, and patient outcomes. The association of burnout with compassion satisfaction, secondary stress, emotional coping strategies and many psychosocial variables, such as institutional support, friendship, and spirituality, have not been well studied. A convenience sample of internal medicine physicians was emailed a survey using validated instruments to explore these associations. The response rate was 337/1021 (33%), with a burnout prevalence of 175/337 (52%). Grit, acceptance, active coping, positive reframing, and strategy planning were associated with lower burnout domains and greater compassion satisfaction. Certain emotional coping strategies such as denial, disengagement, self-blame, substance abuse, and venting were associated with greater burnout and lower compassion satisfaction. Greater institutional support was associated with lower burnout (r?=????.35, p?<?.001), secondary stress (r?=????.14, p?<?.05), and compassion satisfaction (r?=?.28, p?<?.0001). Friendship was associated with lower burnout (r?=????.25, p?<?.0001) and greater compassion satisfaction (r?=?.28, p?<?.0001). This study suggests that amelioration of burnout requires both intrinsic strategies that emphasize physician coping skills as well as extrinsic strategies that address institutional support.

     

All parts of an item are not equal: Effects of phonological redundancy on immediate recall

The process of redintegration is thought to use top-down knowledge to repair partly damaged memory traces. We explored redintegration in the immediate recall of lists from a limited pool of partly phonologically redundant pseudowords. In Experiment 1, four kinds of stimuli were created by adding the syllable /ne/ to two-syllable pseudowords, either to the middle (/tepa/ vs. /tenepa/) or to the end (/tepane/), or adding a different syllable to each item (/tepalo/, /vuropi/). The repeated syllable was thought to be available for redintegration. Lists of two-syllable pseudowords were recalled best, items with a redundant end were intermediate, and items with a redundant middle-syllable were as hard as nonredundant three-syllable items. In Experiment 2, the last syllable was predictable from context but not shared between all stimuli, reducing phonological similarity between items. Performance did not differ from the situation with identicallast syllables. In Experiment 3, a shared first syllable had a detrimental effecton memory. An error analysis showed that beneficial redundancy effects were accompanied by harmful similarity effects, impairing memory for nonredundant syllables. The balance between the two effects depended on syllable position.     

Assessment of tobacco craving by means of the affective image visualization paradigm

Smoking cues that increase craving are subjectively described by smokers as pleasant rather than unpleasant. However, it remains controversial whether the motivational nature of these smoking cues is consistent with an appetitive or aversion-relief model of tobacco craving. In the two studies presented here, the Bioinformational model of emotion proposed by Lang was used to address this issue. In study I, 40 smokers (10 males) assessed a set of tobacco-related pictures and a subset of standard pleasant, neutral, and unpleasant pictures in order to examine how craving relates to the three general dimensions of emotion: valence, arousal, and dominance. Results showed that the tobacco-related images were all assessed as appetitive, and craving was correlated positively with valence (r = .863, p < .0001) and arousal (r = .923, p < .0001) and negatively with dominance (r = −.504, p < .002). In study II, 24 female abstinent smokers were examined using Lang’s startle modulation paradigm in order to assess whether tobacco-related pictures, compared to standard pleasant and unpleasant ones, inhibited the startle response, consistent with an appetitive model of tobacco craving. Contrary to expectations, the startle response during visualization of tobacco-related pictures was more similar in magnitude to the response to unpleasant than to pleasant images, a finding inconsistent with an appetitive model of tobacco craving.
