How accurately can older adults evaluate the quality of their text recall? The effect of providing standards on judgment accuracy

Adults have difficulties accurately judging how well they have learned text materials; unfortunately, such low levels of accuracy may obscure age‐related deficits. Higher levels of accuracy have been obtained when younger adults make postdictions about which test questions they answered correctly. Accordingly, we focus on the accuracy of postdictive judgments to evaluate whether age deficits would emerge with higher levels of accuracy and whether people's postdictive accuracy would benefit from providing an appropriate standard of evaluation. Participants read texts with definitions embedded in them, attempted to recall each definition, and then made a postdictive judgment about the quality of their recall. When making these judgments, participants either received no standard or were presented the correct definition as a standard for evaluation. Age‐related equivalence was found in the relative accuracy of these term‐specific judgments, and older adults' absolute accuracy benefited from providing standards to the same degree as did younger adults.

The effects of emotion on younger and older adults’ monitoring of learning

Age-related differences in memory monitoring appear when people learn emotional words. Namely, younger adults’ judgments of learning (JOLs) are higher for positive than neutral words, whereas older adults’ JOLs do not discriminate between positive versus neutral words. In two experiments, we evaluated whether this age-related difference extends to learning positive versus neutral pictures. We also evaluated the contribution of two dimensions of emotion that may impact younger and older adults’ JOLs: valence and arousal. Younger and older adults studied pictures that were positive or neutral and either high or low in arousal. Participants made immediate JOLs and completed memory tests. In both experiments, the magnitude of older adults’ JOLs was influenced by emotion, and both younger and older adults demonstrated an emotional salience effect on JOLs. As important, the magnitude of participants’ JOLs was influenced by valence, and not arousal. Emotional salience effects were also evident on participants’ free recall, and older adults recalled as many pictures as did younger adults. Taken together, these data suggest that older adults do not have a monitoring deficit when learning positive (vs. neutral) pictures and that emotional salience effects on younger and older adults’ JOLs are produced more by valence than by arousal.     

The effects of computer-based instruction on college students’ comprehension of classic research

Our purpose in this research was to determine the extent to which computer-based instruction can replace conventional teaching in experimental psychology. In Experiment 1, students from an advanced cognition and thinking course participated in a simulation of Schallert’s (1976) study of the role of context in prose comprehension and in a simulation of Carpenter and Just’s (1975) study of sentence-picture verification latencies. Half of the students completed each experiment with the computer, and half were taught traditionally. Comprehension of the purpose and design of the experiments was tested immediately after the laboratory session and 1 month later during the final examination. There were no significant differences between the groups. Several students in Experiment 1 appeared to rush through the experiments and pay little attention to the explanations. In Experiment 2, we studied the effectiveness of computer-based instruction in experimental laboratory sections that did or did not require a follow-up assignment. The second variable was introduced so that some factor of seriousness or importance of the laboratory exercise could be measured. Results from this study indicated that, regardless of the perceived importance of a laboratory exercise, students who studied classic research in a traditional setting comprehended the purpose and design of the experiment better than did the students who worked on the computer. In addition, the students assigned to write up the experiment performed better than did the students who were given no follow-up assignment.     

Can language do the driving? The effect of linguistic input on infants' categorization of support spatial relations

Two experiments explored the effect of linguistic input on 18-month-olds' ability to form an abstract categorical representation of support. Infants were habituated to 4 support events (i.e., one object placed on another) and were tested with a novel support and a novel containment event. Infants formed an abstract category of support (i.e., looked significantly longer at the novel than familiar relation) when hearing the word "on" during habituation but not when viewing the events in silence (Experiment 1) or when hearing general phrases or a novel word (Experiment 2). Results indicate that a familiar word can facilitate infants' formation of an abstract spatial category, leading them to form a category that they do not form in the absence of the word.     

Can performance-feedback accuracy be improved? Effects of rater priming and rating-scale format on rating accuracy

Performance appraisal information is often used for employee feedback and development. Research has found that assessments that are global (i.e., based on broad aspects of performance) and comparative (i.e., explicit interratee comparisons) may be most accurate in terms of Cronbach's (1955) differential accuracy, a type of accuracy that is directly relevant to the provision of feedback. Unfortunately, a global-comparative assessment may not give recipients the most useful diagnostic feedback. In this experiment, an innovative rater-priming manipulation was developed and tested on a sample of 109 participants. The priming manipulation had the effect of improving differential accuracy and providing diagnostic feedback. A 2nd independent variable involving 2 different Behavioral Observation Scale formats also was investigated. Explanations of findings, limitations of this experiment, directions for future research, and implications for performance appraisal practice are discussed.     

Does understanding relational terminology mediate effects of intervention on compare word problems?

The purpose of this study was to assess whether understanding relational terminology (i.e., more, less, and fewer) mediates the effects of intervention on compare word problems. Second-grade classrooms (N=31) were randomly assigned to one of three conditions: researcher-designed word-problem intervention, researcher-designed calculation intervention, or business-as-usual (teacher-designed) control. Students in word-problem intervention classrooms received instruction on the compare problem type, which included a focus on understanding relational terminology within compare word problems. Analyses, which accounted for variance associated with classroom clustering, indicated that (a) compared with the calculation intervention and business-as-usual conditions, word-problem intervention significantly increased performance on all three subtypes of compare problems and on understanding relational terminology, and (b) the intervention effect was fully mediated by students' understanding of relational terminology for one subtype of compare problems and partially mediated by students' understanding of relational terminology for the other two subtypes.     

The credibility of children's testimony: can children control the accuracy of their memory reports?

In previous work with adults (A. Koriat & M. Goldsmith, 1994, 1996c), it was shown that people can enhance the accuracy of their testimony substantially when they (a) are effective in monitoring the correctness of their answers, (b) are free to control their reporting accordingly (i.e., to decide which pieces of information to volunteer and which to withhold), and (c) are given incentives for accurate reporting. A theoretical model was developed, which specifies the critical role of metacognitive monitoring and control processes in mediating free-report memory accuracy. The present study applies that model to examine the strategic regulation of memory accuracy by children. Three experiments indicate that both younger (ages 7 to 9) and older (ages 10 to 12) children can enhance the accuracy of their testimony by screening out wrong answers under free-report conditions but suggest a developmental trend in the level of memory accuracy that is thereby achieved. The implications of the results for the dependability of children's testimony in legal settings are discussed.     

The role of the degree of acquaintance with teachers on students’ interpersonal perceptions of their teacher

Some researchers suggest that the way a teacher is perceived during the first encounter with a classroom group resembles, and therefore is predictive of, later classroom processes as perceived by students. This study investigated the degree to which interpersonal ratings (i.e., control and affiliation), given by secondary school students to teachers unknown to them, are comparable to ratings given by students who are well acquainted with that teacher, by means of a quasi-experimental design. Ratings concerning a teacher students had not met before, based on a 5 min video vignette, were compared to ratings given by students who had been taught by the same teacher for at least a year (N $\,{=}\,$ 489). Students at no acquaintance perceived a teacher’s interpersonal traits in a similar way as students who were familiar with that teacher. It is concluded that students’ early interpersonal perceptions of a teacher largely resemble perceptions formed by students that know this teacher well.     

The effects of time and distance on accuracy of target-directed locomotion: does an accurate short-term memory for spatial location exist?

The present study was an attempt to replicate the findings of an influential set of experiments by Thomson (1980, 1983) in which he demonstrated a highly accurate but transitory short-term memory for target location during locomotion. No evidence of Thomson's rapidly decaying 8 s short-term memory was found in either of the two experiments presented here. The distance to the target, not the elapsed time, was found to be the major variable affecting the accuracy of walks made without the benefit of visual feedback; as target distance increased so did locomotor error. Increasing the elapsed time to more than 8 s between viewing the target and reaching the vicinity of the target had no effect on the accuracy of walks made with eyes closed. When the elapsed time was greater than 30 s, however, performance began to deteriorate. These results suggest, in sharp contrast to Thomson's experiments, that short-term memory for target location decays rather slowly during locomotion. In this regard, short-term memory in locomotor tasks appears to be little different from the kinds of short-term memory associated with other motor acts.     

Jolly fat rats? The effects of diet-induced obesity on territorial fighting

In experiment 1, pairs of young male rats became obese on a palatable and complex diet high in fat, sucrose, and protein. The obese pairs exhibited greater within-group weight variability and, when tested as adults, were significantly more aggressive toward an unfamiliar conspecific than chow-fed controls. The increased aggressivity of obese males was not due to the relatively larger resident-intruder weight disparities in these pairs, since weight-matched pairs of unfamiliar animals were as aggressive toward each other as pairs not matched in body weight (experiment 2). The complex and calorically dense diet may have accelerated the development of the experimental animals, producing subjects whose aggressivity was comparable to that of much older animals.     

The effect of object–valence relations on automatic evaluation

Two experiments tested the effect of co-occurrence of a target object with affective stimuli on automatic evaluation of the target when the relation between the target and the affective stimuli suggests that they have opposite valence. Participants learned about targets that ended an unpleasant noise or a pleasant music. The valence of such targets is opposite to the valence of the affective stimuli that co-occur with them. Participants reported preference for targets that ended noise over targets that ended music, but automatic evaluation measures revealed the opposite preference. This suggests that automatic evaluation is sensitive to co-occurrence between stimuli more than to the relation between the stimuli, and that relational information has a stronger influence on deliberate evaluation than on automatic evaluation. These conclusions support the associative-propositional evaluation model (Gawronski & Bodenhausen, 2006), and add evidence regarding the sensitivity of the evaluative-conditioning effect to relational information.     

Can you get a better deal elsewhere? The effects of psychological contract replicability on organizational commitment over time

Previous research on psychological contracts has focused on whether or not employees feel their employers have fulfilled the promises made to them. Instead, here we examine how perceptions of the external labor market, particularly about whether present psychological contracts could be replicated elsewhere, influence employees’ attachment to their current employers. In a longitudinal study of a diverse employee sample, we found perceptions that psychological contracts could not be replicated elsewhere accounted for a substantial amount of the variance in affective commitment (.38) and normative commitment (.29) and a smaller, but significant, amount of the variance in continuance commitment (.04). We also found significant moderating effects of age, work experience, and career stage on these relationships. The article concludes with implications for psychological contract theory, organizational commitment theory, and management practice.     

Use of positive interventions: Does neuroticism moderate the sustainability of their effects on happiness?

Previous research indicates that performing positive activities boosts happiness. The present studies examined whether neuroticism would moderate the sustainability of the effects of positive activities on happiness. Study 1 showed that the effects of counting blessings/kindness daily for seven days lasted a week after participants stopped performing the activity, but only for low-neuroticism individuals (who reported increased happiness) and not high-neuroticism individuals. However, a week post-intervention, gratitude-/kindness-listing participants were more likely to choose an amusing rather than a sad film, regardless of neuroticism differences. This suggests that behavioral choice is more sensitive to positive intervention effects than self-reported happiness. In Study 2, high-neuroticism individuals who occasionally visualized and wrote about their best possible selves over three weeks were happier than their counterparts in the control condition. The present research illustrates that although neuroticism moderates the sustainability of positive intervention effects, encouraging continuance of positive activities may produce more lasting effects.     

Blue or red? The effects of colour on the emotions of Chinese people

Two experiments were performed to examine the effects of red and blue on the emotional pleasure of Chinese people. Experiment 1 explored the effects of the ‘physical’ colours red and blue on emotion, and the results showed that red induced positive and negative emotion, while blue only induced positive emotion. Experiment 2 further explored the effects of the ‘verbal’ colours red and blue on emotion, and the results showed that red induced only positive emotion, while blue induced neither positive nor negative emotion. The findings indicate that the influence of colour on emotion is rooted in both natural and social associations. For Chinese, the associations between blue and positive emotion, and red and negative emotion, were natural associations; however, the associations between red and positive emotion were social associations. Moreover, physical colour and verbal colour stimuli induced emotions by activating different mechanisms: physical colour induced emotions via both natural and social associations, whereas verbal colour induced emotions via social associations.     

The influence of linguistic labels on source‐monitoring decisions

Three studies explored the extent to which people use various object features, including linguistic label, shape, and category membership, to make decisions about the source of their memories. To isolate the influence of each feature, we used items that were related in the following four ways: as synonyms, as similar in shape and category membership, as homographs, or as unrelated. Participants read sentences and either saw or imagined a picture of the critical word's referent. Experiment 1 showed that participants committed more source errors for synonyms (e.g., rabbit and bunny) than for objects that were conceptually and perceptually similar (e.g., doughnut and bagel), which produced more errors than unrelated items. However, there was no effect of label, as people did not have more errors for homographs (e.g., baseball bat and flying bat) than unrelated items. In Experiment 2, presenting the critical word at study was not sufficient to lead people to use an item's label to make source decisions. However, Experiment 3 showed more source errors for homographs than unrelated pairs when semantic context was minimised at study, suggesting that people can use linguistic labels to make source decisions when other information is unavailable.     

Can thematic roles leave traces of their places?

An important question in the study of language production is the nature of the semantic information that speakers use to create syntactic structures. A common answer to this question assumes that thematic roles help to mediate the mapping from messages to syntax. However, research using structural priming has suggested that the construction of syntactic frames may be insensitive to variations in thematic roles within messages (Cognition 35 (1990) 1; Psychological Review 99 (1992) 150). Because these studies involved structural alternations whose syntax covaries with the order of thematic roles, it is difficult to assess any independent contribution that role information may make to the positioning of phrases. In this study, we primed the order of the roles without changing the syntactic structure of the sentences produced, and found that the order of the roles was influenced by the priming manipulation. This implies that thematic roles or the features that differentiate them are active within the mapping between messages and sentence structures.     

How do we judge our confidence? Differential effects of meta-memory feedback on eyewitness accuracy and confidence

According to the cue–belief model, we assess confidence in our memories using self-credibility cues that reflect beliefs about our memory faculties. We tested the influence of meta-memory feedback on self-credibility cues in the context of eyewitness testimony, when feedback was provided prior to “testifying” via a memory questionnaire (Experiment 1) and after an initial memory questionnaire but before participants had to retake it (Experiment 2). Participants received feedback (good score, bad score, or none) on a fictitious scale purported to predict eyewitness memory ability. Those given good score feedback before testifying were more confident (but no more accurate) than those given bad score feedback. Feedback also affected confidence (good increased and bad decreased) and accuracy (good increased) after testifying but only on leading questions. These differential effects of meta-memory feedback on confidence for normal and leading questions are not explained by the cue–belief model. Implications for our confidence judgments are discussed.
