公正世界信念对记忆偏差的影响

公正世界信念指人们需要相信他们所处的世界是一个公正有序的世界。本研究考察的是公正世界信念是否影响人们的记忆,让人产生记忆偏差。实验一中,被试首先阅读一则彩票中奖的新闻,然后阅读关于中奖者人品的描述,最后被试需要回忆中奖金额。结果发现,中奖者的个性品质影响对奖金数额的记忆。实验二中,两组被试分别阅读一则维护公正世界信念或威胁公正世界信念的无关故事,接下来程序与实验一相同。结果发现,预先激活的公正世界信念状态与中奖者个性品质在记忆结果上存在显著的交互效应。结果表明,公正世界信念能够导致记忆偏差。     

Memory limitations in the oral reading comprehension of fourth-grade children

Four experimental tasks were devised to locate the nature of memory processing limitations in fourth-grade children's oral reading comprehension. Experiment 1 showed that in the reading of very simple prose children can consciously bring memory strategies into play. Even in simple and short prose passages, however, memory limitations upon performance are operative. Experiment 2 showed that in prose of moderate difficulty “executive” memory processes are impaired, such that children can no longer employ memory strategies to facilitate subsequent recall. Experiment 3 showed that in the reading of passages high in difficulty, even short-term recall is impaired. These results were interpreted as consistent with the La Berge and Samuels theory of automatic information processing in reading.     

Comparison of active and purely visual performance in a multiple-string means-end task in infants

The aim of the present study was to understand what factors influence infants’ problem-solving behaviours on the multiple-string task. The main question focused on why infants usually solve the single string-pulling task at 12 months at the latest, whereas most 16-month-old infants still cannot solve the task when several strings are presented, only one of which is attached to the desired object. We investigated whether this difficulty is related to infants’ ability to inhibit their spontaneous immediate actions by comparing active and purely visual performance in this task. During the first part of the experiment, we assessed the ability of infants aged 16–20 months to solve the multiple-string task. The infants were then divided into three groups based on performance (a “failure” group, an “intermediate” group, and a “success” group). The results of this action task suggest that there were differences in infants’ performance according to their level of inhibitory control of their preferred hand. In the second part of the experiment, the three groups’ predictive looking strategies were compared when seeing an adult performing the task. We found that only infants who successfully performed the action task also visually anticipated which string the adult had to pull in the visual task. Our results suggests that inhibitory control was not the only factor influencing infants’ performance on the task. Furthermore, the data support the direct matching hypothesis (Rizzolatti and Fadiga, 2005), according to which infants need to be able to perform actions themselves before being able to anticipate similar actions performed by others.     

Effect of a simple experimental control: The recall constraint in Sternberg's memory scanning task

This study was aimed at determining how a simple experimental control—recalling the sequence of digits in the order they were presented—may affect quantitative and qualitative performance in Sternberg's short-term memory scanning paradigm. First, the presence or absence of this constraint was shown to have practically no effect on the relationship between sequence length and mean response time: the two general laws proposed by Sternberg were found to hold true in both experimental conditions. However, subjects who had to recall the digit sequence were consistently slower than those who did not, and the yes response curves of the two experimental conditions differed in shape. Moreover, correlations between parameters of the linear function and various aptitude scores showed that this task was linked to the memory span only when the participants had to recall the digit sequence. If our results are confirmed, they should help to improve the interpretation of the data collected in many studies that use this paradigm in cognitive psychology as well as in neuroscience of memory.     

Forgetting to forget: On the duration of voluntary suppression of neutral and emotional memories

Can we control the content of our memory and forget what we do not want to think about by an act of will? If so, is forgetting temporary or permanent, and is it independent of the nature of what we wish to forget? Using Anderson and Green’s (2001) “think/no-think” paradigm with neutral and emotional nouns, we found in agreement with other studies that memory for neutral words was reduced instantly upon repeated attempts at suppression. However, the effect was temporary and vanished after a period of one week, which strongly suggests that intended memory suppression interferes with immediate retrieval but does not lead to long-term forgetting. Furthermore, the amount of training that clearly reduced immediate recall of neutral items did not at all reduce recall of emotional items. This finding is in accordance with the notion that emotional items have a higher degree of salience and tend to attract more attention than neutral items.     

The effects of justice motivation on memory for self- and other-relevant events

We examined whether people might distort and selectively remember the past in ways that enable them to sustain a belief in a just world (BJW; Lerner, M. J. (1980). The belief in a just world: A fundamental delusion. New York: Plenum Press). In Study 1, recall of a lottery prize reflected participants’ justice concerns, such that the average lottery amount recalled was lowest when a “bad” versus “good” person won. In Study 2, an unrelated experience of just world threat (versus affirmation) enhanced biased recall of the lottery prize when the winner was undeserving. In Study 3, participants who experienced a fortuitous bad break selectively remembered more bad deeds from their recent past, whereas participants who experienced a good break selectively remembered more good deeds. Study 4 demonstrates that such selective memory biases specifically serve to portray chance outcomes as more fair. Taken together, these findings offer support for the notion that reconstructing and selectively recalling the past can serve to sustain a BJW.     

The influence of depression symptoms on exploratory decision-making

People with symptoms of depression show impairments in decision-making. One explanation is that they have difficulty maintaining rich representations of the task environment. We test this hypothesis in the context of exploratory choice. We analyze depressive and non-depressive participants’ exploration strategies by comparing their choices to two computational models: (1) an “Ideal Actor” model that reflectively updates beliefs and plans ahead, employing a rich representation of the environment and (2) a “Naïve Reinforcement Learning” (RL) model that updates beliefs reflexively utilizing a minimal task representation. Relative to non-depressive participants, we find that depressive participants’ choices are better described by the simple RL model. Further, depressive participants were more exploratory than non-depressives in their decision-making. Depressive symptoms appear to influence basic mechanisms supporting choice behavior by reducing use of rich task representations and hindering performance during exploratory decision-making.     

Cognitive effects of language on human navigation

Language has been linked to spatial representation and behavior in humans, but the nature of this effect is debated. Here, we test whether simple verbal expressions improve 4-year-old children’s performance in a disoriented search task in a small rectangular room with a single red landmark wall. Disoriented children’s landmark-guided search for a hidden object was dramatically enhanced when the experimenter used certain verbal expressions to designate the landmark during the hiding event. Both a spatial expression (“I’m hiding the sticker at the red/white wall”) and a non-spatial but task-relevant expression (“The red/white wall can help you get the sticker”) enhanced children’s search, relative to uncued controls. By contrast, a verbal expression that drew attention to the landmark in a task-irrelevant manner (“Look at this pretty red/white wall”) produced no such enhancement. These findings provide further evidence that language changes spatial behavior in children and illuminate one mechanism through which language exerts its effect: by helping children understand the relevance of landmarks for encoding locations.     

Use of experienced retrieval ease in self and social judgments

People base judgments from memory on both the content of the information they retrieve and the ease they experience in retrieving it (Schwarz, N., Bless, H., Strack, F., Klumpp, G., Rittenauer-Schatka, H., & Simons, A. (1991). Ease of retrieval as information: another look at the availability heuristic. Journal of Personality and Social Psychology, 61, 195-202). Four studies demonstrate that people rely relatively more on the experienced ease of recall when making judgments about the self compared to judgments about others. This pattern was found for judgments of an “average” (Study 1a) or specific (Study 1b) other. Subjective retrieval ease was less informative when people were relatively less familiar with the specific other person. Providing an alternative explanation for the experienced difficulty of recall affected self, but not social, assessments (Study 2). In addition, the effect generalized to risk judgments about a state of the world; namely, the safety of one’s town (Study 3). A deeper appreciation of when and why people rely on different sources of accessible information when making judgments may help in understanding and reducing social conflict.     

Effects of ownership expressed by the first-person possessive pronoun

The present study examined the behavioral effects of the first-person possessive pronoun. In each trial, a noun (e.g. cup or bread) was presented to participants after visual presentation of a possessive pronoun “wo de” (Chinese for “my”) or “ta de” (Chinese for “his”), which formed ownership. Half participants were assigned to contextual encoding (CE) condition in which they were required to judge whether they liked the item expressed by a noun from the first or third-person perspective. The rest were assigned to perceptual encoding (PE) condition in which they were asked to judge what color the noun was. A subsequent recall test was performed. The results showed that there were significant memory and response advantages for nouns in “my” ownership under both conditions. The results were discussed with reference to self-specificity and other effects in the current study.     

The Relation of ERP Components to Complex Memory Processing

The relation between various ERP components generated during encoding of a word and its subsequent recall were investigated using a “rote” serial-order and an “elaborative” category memory task. Words (flashed separately) were time-locked to EEG recordings from 21 cortical sites. ERP components from the five subjects having the highest recall scores were compared to the five lowest scoring subjects. Results based on the P200 peak amplitude data as well as the N400 and late positive component peak amplitude and latency data suggest that anterior and posterior distributional differences are elicited during encoding of words for rote and elaborative memory tasks. Furthermore, strong individual differences in these patterns were found as a function of task. A tentative argument was made that the obtained anterior and posterior differences may index different word feature selection and encoding processes, which are differentially utilized by high and low recallers.     

Driving without awareness: The effects of practice and automaticity on attention and driving

This research examined the development of proceduralised “driving without awareness” in a driving simulator by paying participants to drive a simulated road regularly over 12 weeks of testing. This longitudinal research paradigm is a significant departure from previous studies which have examined drivers in a conscious attentional mode using short experimental sessions or cross-sectional designs comparing expert and novice performance. During each session, participants took two “trips” on the simulated road; sometimes travelling on a “to and from” journey on one half of the road, sometimes traversing the entire road in one direction. A range of measures, including driving performance, vehicle detection, perceptual speed regulation, and hazard reactions were collected. The results showed the development of driving patterns and changes in object detection performance indicative of proceduralised driving. Speed and lane position variability quickly decreased with practice, as did participants’ subjective experiences of driving difficulty. Performance on an embedded detection task appeared to become a proceduralised part of the driving task, becoming highly efficient in later stages of the experiment. The changes in attentional focus and driving performance over time provide new light on previous research findings and allow us to critically re-examine several established models of driver behaviour.     

Prototypes of race and gender: The invisibility of Black women

Research on racial and gender stereotyping typically focuses on the role of one of these social categories at a time rather than race/gender combinations. We suggest that the relative non-prototypicality of Black women’s race and gender results in their “invisibility” relative to White women and to Black and White men ( [Fryberg and Townsend, 2008] and [Purdie-Vaughns and Eibach, 2008]). Two studies address whether Black women go “unnoticed” and their voices “unheard,” by examining memory for Black women’s faces and speech contributions. We found that photos of Black women were least likely to be recognized (Study 1), and statements said by a Black woman in a group discussion were least likely to be correctly attributed (Study 2) compared to Black men and White women and White men. The importance and implications of invisibility as a unique form of discrimination are discussed.     

Memory bias for threatening information in anxiety and anxiety disorders: a meta-analytic review

Although some theories suggest that anxious individuals selectively remember threatening stimuli, findings remain contradictory despite a considerable amount of research. A quantitative integration of 165 studies with 9,046 participants (clinical and nonclinical samples) examined whether a memory bias exists and which moderator variables influence its magnitude. Implicit memory bias was investigated in lexical decision/stimulus identification and word-stem completion paradigms; explicit memory bias was investigated in recognition and recall paradigms. Overall, effect sizes showed no significant impact of anxiety on implicit memory and recognition. Analyses indicated a memory bias for recall, whose magnitude depended on experimental study procedures like the encoding procedure or retention interval. Anxiety influenced recollection of previous experiences; anxious individuals favored threat-related information. Across all paradigms, clinical status was not significantly linked to effect sizes, indicating no qualitative difference in information processing between anxiety patients and high-anxious persons. The large discrepancy between study effects in recall and recognition indicates that future research is needed to identify moderator variables for avoidant and preferred remembering.     

Additive factors and stages of mental processes in task networks

To perform a task a subject executes mental processes. An experimental manipulation, such as a change in stimulus intensity, is said to selectively influence a process if it changes the duration of that process leaving other process durations unchanged. For random process durations a definition of a factor selectively influencing a process by increments is given in terms of stochastic dominance (also called “the usual stochastic order”). A technique for analyzing reaction times, Sternberg’s Additive Factor Method, assumes all the processes are in series. When all processes are in series, each process is called a stage. With the Additive Factor Method, if two experimental factors selectively influence two different stages by increments, the factors will have additive effects on reaction time. An assumption of the Additive Factor Method is that if two experimental factors interact, then they influence the same stage. We consider sets of processes in which some pairs of processes are sequential and some are concurrent (i.e., the processes are partially ordered). We propose a natural definition of a stage for such sets of processes. For partially ordered processes, with our definition of a stage, if two experimental factors selectively influence two different processes by increments, each within a different stage, then the factors have additive effects. If each process selectively influenced by increments is in the same stage, then an interaction is possible, although not inevitable.     

Retrieval strategies in recall of natural categories and categorized lists

Experiments 1 and 2 examined the effect of retrieval strategies on 3 or 12 min of recall from a natural category. Experiment 3 examined the effect of strategy on 6 min of recall from a subset of a category presented as a list. In Experiments 1 and 2, a large recall deficit was produced by retrieval strategies involving recall in alphabetic order and by size of the words' referents, relative to free recall. In Experiment 3, four strategies, alphabetic, size, serial order, and free recall, gave similar levels of recall after 6 min, though the growth rate of the cumulative output functions differed among the strategies. An extension of the search of associative memory (SAM) model of Raaijmakers and Shiffrin was developed to explain these results; the new model postulates attention sharing among probe cues and the use of idiosyncratic strategies for free recall from natural categories.     

The importance of differentiation in young children’s acquisition of expertise

In a short-term longitudinal study, stories told about novel creatures conveyed information varying in its capability for differentiating. Depending on the context, a bodily feature could be functionally undifferentiated (FUF), meaning that its subtypes (e.g., eyes of two forms) shared a generic function (“seeing”), or functionally differentiated (FDF), meaning that each subtype’s function was unique to it (e.g., only a “hooded eye” could “see in a sandstorm”). 5- to 6-year-olds who heard 8 stories, but not those who heard only 4, cited FDFs more than FUFs in a pair-justification test of judged similarity; and their delayed recall of specific story events was greater when FDFs rather than FUFs were involved. In the absence of direct instruction, young children show sensitivity to the degree of differentiation afforded by feature-function relations.     

What counts as “good” quantitative research and what can we say about when to use quantitative and/or qualitative methods?

In response to points raised by Dawson, Fischer, and Stein; Stam; and Stiles, the author delineates what counts as “good” quantitative research according to his proposal for explicitly interpretive quantitative methods. The key points concern how to employ these methods, not which quantitative methods we should use—“strong” rather than “soft” or vice versa. The author discusses ways in which what others would consider “strong” quantitative procedures can be extremely useful, although he argues that these procedures are interpretive. The reconceptualization of quantitative research offered here also suggests that the distinction between quantitative and qualitative research is much less fundamental than most researchers think. In a consideration of what we can say in general about when to employ quantitative and/or qualitative methods, the author returns to the theme of the limits of possible understanding in psychology.     

Acting or listening: Adult age differences in source recall of enacted and nonenacted statements

This study explored age-related differences in item and source recall of enacted and nonenacted items in a sample of healthy adults between the ages of 35 and 80 years (N=1,000). Participants were screened on a variety of demographic, psychometric, and biological variables. They were presented with sentences (e.g., Lift the book) that they either read or enacted. They were then asked to recall the object of each stimulus sentence (item recall) and to identify its format of encoding (source recall). Age-related decrements were observed both in item and source memory, although age differences in source memory were more accentuated than in item memory. Further, the results indicated an overall impairment of source memory across age when individual differences in the demographic, psychometric, and biological variables were taken into consideration.     

The endurance of children's working memory: a recall time analysis

We analyze the timing of recall as a source of information about children’s performance in complex working memory tasks. A group of 8-year-olds performed a traditional operation span task in which sequence length increased across trials and an operation period task in which processing requirements were extended across trials of constant sequence length. Interword pauses were longer than are commonly found in immediate serial recall tasks yet shorter than for reading span. These pauses increased with the demands of recall, decreased across the output sequence, and were to some extent predictive of scholastic ability. Overall, timing data illustrate that recall in working memory tasks involves subtle processes of item access rather than simple readout of information from an immediate store.
