Response monitoring and expectancy in random serial RT tasks

Two different sequential patterns have been reported in serial reaction-time (RT) tasks with random stimulus sequences, depending on the response-to-stimulus interval (RSI). When RSI is short a first-order repetition effect and a higher order benefit-only pattern are found, and when RSI is long a cost-benefit pattern is observed. In a series of three experiments, we found that the patterns are not unique for spatial dimensions, and that the benefit-only pattern does not appear for irrelevant stimulus features. The cost-benefit pattern, on the other hand, can shift to irrelevant locations, but not to irrelevant colour. Distributional analyses of the sequential effects demonstrate that the first-order repetition effect can be dissociated from the higher order effects. The results are interpreted as support for the role of response monitoring in the development of the benefit-only pattern at short RSI, while the first-order repetition effect is explained as repetition priming. With a long RSI, the cost-benefit pattern is confirmed as a low-level subjective expectancy process, which is primarily controlled by stimulus location. The data clearly strengthen the support for three different processes generating sequential effects in random serial RT tasks.     

Factors Influencing Men's Interest in Gene Testing for Prostate Cancer Susceptibility

Interest in genetic testing for inherited cancer susceptibility is high in the general population. Women at risk for BRCA1 and BRCA2 mutations represent the best-studied population undergoing genetic testing for cancer susceptibility. However, it is unclear whether factors influencing interest in genetic testing in women are directly applicable to men. We designed a study to examine factors associated with men's interest in genetic testing to identify prostate cancer susceptibility. Our sample consisted of 267 men present in waiting rooms of a urology clinic in an urban area. We examined whether the concept of monitoring could be used to predict the interest of men in a genetic test for prostate cancer susceptibility. Our results indicated that monitoring trait was positively associated with interest in genetic testing in these men, but principally for patients rather than nonpatients. Moreover we found that monitoring was associated with over estimation of risk in those men with prostate cancer. Other factors found to influence interest in genetic testing included recommendation by a doctor, family history of prostate cancer, and cost. This study indicated that interest in genetic testing and estimation of risk is influenced by a complex interaction between both psychological factors (monitoring) and nonbehavioral factors (such as patient status, cost, and doctor recommendation).     

The cognitive regulation of emotions: The role of success versus failure experience and coping dispositions

Attention deployment and generating specific types of cognitions are central cognitive mechanisms of emotion regulation. Two groups of hypotheses make contradicting predictions about the emotion-cognition relationship. The moodcongruency hypothesis expects the emergence of mood-congruent cognitions (i.e., negative mood leads to negative and positive mood to positive cognitions). Similarly, a substantial body of research suggests that negative mood induces selffocus, whereas positive mood elicits an external focus of attention. The moodrepair hypothesis, on the other hand, assumes that persons in a negative mood state summon thoughts incongruent with that state and divert attention away from the self. However, the temporal sequence of cognitions assessed as well as coping dispositions, such as vigilance and cognitive avoidance, may moderate these relationships. Positive and negative emotional states were elicited by exposing the participants to the experience of success or failure in a demanding cognitive task. Cognitions that were present after emotion induction were assessed by means of a thought-listing procedure. For the total sample, results clearly confirmed the moodcongruency hypothesis. Thought order was a critical factor only for changes in self-focus. Thought valence (positive, neutral, negative) as well as self-focus were substantially influenced by coping dispositions.     

Mindfulness and negative affectivity in real time: a within-person process model

ABSTRACT

To extend our understanding of the proximal etiology of personality pathology, this study examined the dynamic, in-the-moment relations between mindfulness and negative affectivity (NA; emotional lability, anxiousness, separation insecurity) as defined by the alternative model for personality disorders. We tested predictions based upon the Monitor and Acceptance Theory that when people monitored their attention judgmentally, their state NA would be higher than usual; by contrast, when they monitored their attention nonjudgmentally, their state NA would be lower than usual. Sixty-five undergraduates participated in an experience sampling study wherein they completed five reports per day for eight days about their states of mindfulness and NA. Multi-level models revealed an interaction wherein participants exhibited more state NA when they monitored their attention judgmentally than when they monitored their attention nonjudgmentally. Analyses of simple slopes revealed that participants exhibited more state NA than usual when they monitored their attention judgmentally. These findings emerged for only one of two attention monitoring processes, however: monitoring relations between thoughts, emotions, and behaviours, but not monitoring sensory stimuli. Analyses including non-reactivity instead of nonjudgment replicated these findings. Implications for theory, research, and treatment are discussed.     

When Knowing Becomes Remembering: Individual Differences in Susceptibility to Suggestion

In two experiments, the authors explored factors that might influence a person's tendency to make source-monitoring errors about autobiographical memories. In the first experiment, undergraduates retrieved a memory from childhood (a) that was known about but not remembered, (b) that was remembered, or (c) for which they were unsure of their memory's source. After writing down the memory, experimental groups listened to a guided visualization tape and answered questions about the event—interventions designed to help them focus on details of their memory. Controls also retrieved and wrote down a memory; however, instead of visualizing the memory, they were instructed to conduct a visual search task. Results indicated that guided visualization led participants to rate known memories closer to remembered events. A second experiment examined individual difference variables that might be related to this know-to-remember shift. Results indicated that extraversion, external locus of control, a memory that conveyed fear, and overall affective content predicted this rating. The applicability of these findings to the psychotherapy process is discussed.     

Seeing photos makes us read between the lines: The influence of photos on memory for inferences

Three studies examined how photos accompanying stories could contribute to people drawing inferences about outcomes from the stories and subsequently claiming that they had read what had actually only been inferred. Subjects read short stories designed to induce inferences about their conclusions (e.g., “Sabrina dropped the delicate vase” invites the inference that the vase broke) accompanied by a photo depicting the likely conclusion (the broken vase), a photo depicting a detail of the story but not the conclusion (the vase before it was dropped), or no photo. Results showed that seeing photographs consistent with inferred conclusions led people to falsely claim that they read those conclusions. Photo-boosted inferences were held with high confidence and were robust over time. Falsely recalled inferences were sometimes accompanied by false claims to have seen a photo depicting the inferred events when another photo or no photo had actually be seen. These findings support the source monitoring framework's prediction that people can mistakenly attribute their internally generated inferences about what occurred to externally derived sources when they have photographic “evidence” consistent with the inferred conclusions.     

Age Differences in Output-Monitoring Accuracy

ABSTRACT

Output monitoring refers to memory for whether an intended action has been completed. Failures in output monitoring can lead to action repetitions or action omissions. Output monitoring is difficult for both younger and older adults, but few studies have examined age differences in output monitoring. Two experiments using a picture-based prospective memory task with an output-monitoring component were conducted to investigate the role of increased contextual detail and pre-exposure on output-monitoring accuracy in younger and older adults. Across the two experimental manipulations older adults demonstrated less accurate output monitoring by primarily committing errors of repetition. Pre-exposure to targets resulted in worse output-monitoring accuracy for both younger and older adults.     

The impact of error frequency on errorless and errorful learning of object locations using a novel paradigm

ABSTRACT

Errorless learning (EL) is an approach in which errors are eliminated or reduced as much as possible while learning of new information or skills. In contrast, during trial-and-error???or errorful???learning (TEL) errors are not reduced and are often even promoted. There is a complex and conflicting pattern of evidence whether EL or TEL may result in better memory performance. One major confound in the extant literature is that most EL studies have not controlled for the number of errors made during TEL, resulting in a large variability in the amount of errors committed. This variability likely explains why studies on the cognitive underpinnings of EL and TEL have produced mixed findings. In this study, a novel object-location learning task was employed to examine EL and TEL in 30 healthy young adults. The number of errors was systematically manipulated, allowing us to investigate the impact of frequency of errors on learning outcome. The results showed that recall from memory was significantly better during EL. However, the number of errors made during TEL did not influence the performance in young adults. Altogether, our novel paradigm is promising for measuring EL and TEL, allowing for more accurate analyses to understand the impact of error frequency on a person’s learning ability and style.     

Look who's talking! Facial appearance can bias source monitoring

When we see a stranger's face we quickly form impressions of his or her personality, and expectations of how the stranger might behave. Might these intuitive character judgements bias source monitoring? Participants read headlines “reported” by a trustworthy- and an untrustworthy-looking reporter. Subsequently, participants recalled which reporter provided each headline. Source memory for likely-sounding headlines was most accurate when a trustworthy-looking reporter had provided the headlines. Conversely, source memory for unlikely-sounding headlines was most accurate when an untrustworthy-looking reporter had provided the headlines. This bias appeared to be driven by the use of decision criteria during retrieval rather than differences in memory encoding. Nevertheless, the bias was apparently unrelated to variations in subjective confidence. These results show for the first time that intuitive, stereotyped judgements of others' appearance can bias memory attributions analogously to the biases that occur when people receive explicit information to distinguish sources. We suggest possible real-life consequences of these stereotype-driven source-monitoring biases.
