Effects of modality on subjective frequency estimates and processing of spoken and printed words

Previous research (Garber & Pisoni, 1991; Pisoni & Garber, 1990) has demonstrated that subjective familiarity judgments for words are not differentially affected by the modality (visual or auditory) in which the words are presented, suggesting that participants base their judgments on fairly abstract, modality-independent representations in memory. However, in a recent large-scale study in Japanese (Amano, Kondo, & Kakehi, 1995), marked modality effects on familiarity ratings were observed. The present research further examined possible modality differences in subjective ratings and their implications for word recognition. Specially selected words were presented to participants for frequency judgments. In particular, participants were asked how frequently they read, wrote, heard, or said a given spoken or printed word. These ratings were then regressed against processing times in auditory and visual lexical decision and naming tasks. Our results suggest modality dependence for some lexical representations.     

Awakenings: subjective and objective relationships

Electroencephalographic measures of awakenings and subjective estimates of amount and frequency of awakenings were compared. The subjects were 65 men and 69 women between 50 and 70 yr. of age; their scores showed ranges on these measures. The relationships between the measures were low. Analyses of scores on the perceptual task indicate the reasons for the low relationship. The functional meaning of these findings is discussed.     

Sleep among presentations of Attention-Deficit/Hyperactivity Disorder: Analysis of objective and subjective measures

Background/ObjectiveTo examine subjective and objective sleep patterns in children with different Attention-Deficit/Hyperactivity Disorder (ADHD) presentations. Method: We assessed 92 children diagnosed with ADHD (29 ADHD-Inattentive [ADHD-I], 31 ADHD-Hyperactive/Impulsive [ADHD-H/I], and 32 ADHD-Combined [ADHD-C)]) aged 7–11 years. The Pediatric Sleep Questionnaire (PSQ), Pediatric Daytime Sleepiness Scale (PDSS), and a sleep diary were used as subjective sleep measures, and polysomnography was used to objectively assess sleep quantity, quality, and fragmentation. Results: Subjective data showed impaired sleep in 12.7% of the sample. No significant differences were found between ADHD presentations in any objective and subjective sleep variable. Nevertheless, data on sleep fragmentation suggested a worse sleep continuity for the ADHD-H/I group, and correlation analyses confirmed that sleep is affected by age. Conclusions: Children with ADHD may suffer from sleep breathing problems and daytime sleepiness, as reported by their parents, even when their total sleep time and sleep efficiency are not affected. It seems that sleep in this population does not largely vary as a function of the ADHD presentation. Sleep in children with ADHD evolves with age.     

Investigating the subjective reports of rejection processes in the word frequency mirror effect

We sought to systematically investigate how participants subjectively classify the basis of their recognition memory judgments for low and high word frequency items. We found that participants more often reported rejection processes related to the increased perceived memorability for unstudied low word frequency items (relative to high word frequency items), rather than classifying their decision on a lack of familiarity. Experiment 2 replicated this pattern and demonstrated context variability and word frequency independently influenced the subjective classifications for correct rejections. Results of Experiment 3 revealed that these differences are dependent upon having experience with both low and high frequency items. Overall, these data suggest participants’ rejection of low frequency items is more strongly related to judgments of perceived memorability, but only when they are presented in the context of high frequency items. The results are discussed in relation to distinctiveness and expected memorability.     

Serotonin transporter genetic variation and biased attention for emotional word stimuli among psychiatric inpatients

The short allele in a variable repeat sequence of the promoter region of the serotonin transporter gene (5-HTTLPR) has been associated with stronger activation in brain regions critical for processing emotional stimuli. The authors examined whether variants of the 5-HTTLPR promoter polymorphism were also associated with individual differences in attentional biases for emotional stimuli. Words related to anxious and dysphoric emotional states were presented to psychiatric inpatients in a standard dot-probe reaction time task. Compared with participants with two long alleles, carriers of the short 5-HTTLPR allele exhibited a stronger attentional bias for anxious word stimuli. No genetic group difference was observed for dysphoric word stimuli. Findings from this preliminary study highlight the potential for integrating genetic and cognitive models of psychopathology.     

Assessing the effectiveness of conflict management training in a health sector organization: evidence from subjective and objective indicators

This study assessed the effectiveness of an intervention for handling interpersonal conflicts at work. In contrast to the mainstream approach in the health care industry, which focuses on developing formal systems of conflict resolution, our intervention consisted of enhancing health care workers’ conflict management skills through training. A pre- and post-test nonequivalent comparison group design was used (intervention group = 258 workers; comparison group = 243 workers). Participants perceived that the training was successful in reducing the number and intensity of conflicts with co-workers, patients, and patients’ relatives. Moreover, organizational indicators calculated on the basis of data obtained from human resources (HR) records show that the intervention was effective, insofar as the number of requests for third-party interventions to mediate conflicts at work, the number of patients’ complaints, and the level of absenteeism all decreased for trained workers, whereas workers from the comparison group exhibited no corresponding changes over time. In the light of these results, this article discusses the design of conflict management measures which could help improve both employees’ well-being and organizational productivity.     

Implicit word activation during pre-recognition processing influences correct recognition and estimates of presentation frequency

False recognition of new test words is higher for experimental lures (e.g., universal) with initial phonemes identical to studied words (e.g., university) than for control lures. A proposed mechanism to explain this phenomenon involves implicit activation of potential solution words during the brief period of uncertainty immediately following onset of a spoken study word. Two experiments examined whether the presumed pre-recognition processing during the stimulus discovery phase of spoken word identification increased familiarity of a studied word, thereby increasing correct recognitions and estimates of presentation frequency. Critical test words were presented a single time during study in Experiment 1, and their phonologically related words were presented one, two, or three times. Correct recognition and frequency estimates of targets were enhanced by multiple presentations of associates sharing initial phonemes. Experiment 2 provided a replication with five repetitions of phonological associates during study and two study presentations of critical test words. The results of these two experiments confirmed a necessary theoretical consequence of the implicit activation mechanism that has been invoked to explain the effects of phonological similarity on false recognition.     

Epistemic justification: its subjective and its objective ways

Objective standards for justification or for being a reason would be desirable, but inductive skepticism tells us that they cannot be presupposed. Rather, we have to start from subjective-relative notions of justification and of being a reason. The paper lays out the strategic options we have given this dilemma. The paper explains the requirements for this subject-relative notion and how they may be satisfied. Then it discusses four quite heterogeneous ways of providing more objective standards, which combine without guaranteeing complete success.     

Disqualified and qualified poor sleepers: subjective and objective variables

Sleep laboratory studies of patients complaining of insomnia have demonstrated discrepancies between subjective reports and electroencephalograph (EEG)-recorded measures. In our research studies on sleeping aids, 60% of the self-described poor sleepers who reported usual sleep latencies of at least 45 min did not meet the laboratory qualification criterion of a 30-min or longer sleep latency. To learn to predict who would qualify for our studies, we compared 30 laboratory-qualified poor sleepers (QPS) with 30 laboratory-disqualified poor sleepers (DPSs) on subjective report, mood, and all-night sleep laboratory variables. QPSs had significantly lower sleep efficiency and total sleep time in the laboratory, but these differences were due to the longer sleep latencies (50.7 +/- 27.8 min vs. 15.2 +/- 6.1 min) of the QPS group. QPSs and DPSs differed significantly in their morning estimates of their laboratory sleep latencies; as a group, QPSs gave an accurate estimate (51.6 +/- 27.8 min), but DPSs were significantly more likely to exaggerate their sleep latencies. Although we did not identify ways of predicting which poor sleepers would show sleep-onset insomnia in the sleep laboratory, we did find that, in this young, healthy population, there are poor sleepers who give an accurate report of a rather severe sleep-onset insomnia.

Subjective judgments of spelling-sound correspondences: Effects of word regularity and word frequency

Subjects asked to judge which of two pronunciations of a letter sequence is typical of how that sequence is pronounced in English showed a strong tendency to nominate the linguistically “regular” word in preference to the “irregular” or “exceptional” word. Experiment 1 showed that this tendency was uninfluenced by the frequencies of the words being compared. The effect of regularity was replicated in Experiment 2, which also demonstrated the importance of the method of cuing the common letter sequence; when it was printed beside the words being judged, a stronger regularity effect was obtained than when the words were presented alone. Both experiments also showed a variation in the subjective strength of spelling-sound correspondences, and it was concluded that all-or-nothing conceptualizations of “rules” and "regularity" are oversimplifications. The implications of the findings for the concept of analogies in pronunciation were also considered.     

Letter position information and printed word perception: the relative-position priming constraint

Six experiments apply the masked priming paradigm to investigate how letter position information is computed during printed word perception. Primes formed by a subset of the target's letters facilitated target recognition as long as the relative position of letters was respected across prime and target (e.g., "arict" vs. "acirt" as primes for the target "apricot"). Priming effects were not influenced by whether or not absolute, length-dependent position was respected (e.g., "a-ric-t" vs. "arict"/"ar-i-ct"). Position of overlap of relative-position primes (e.g., apric-apricot; ricot-apricot; arict-apricot) was found to have little influence on the size of priming effects, particularly in conditions (i.e., 33 ms prime durations) where there was no evidence for phonological priming. The results constrain possible schemes for letter position coding.     

Exploring the additive effects of stimulus quality and word frequency: The influence of local and list-wide prime relatedness

Stimulus quality and word frequency produce additive effects in lexical decision performance, whereas the semantic priming effect interacts with both stimulus quality and word frequency effects. This pattern places important constraints on models of visual word recognition. In Experiment 1, all three variables were investigated within a single speeded pronunciation study. The results indicated that the joint effects of stimulus quality and word frequency were dependent upon prime relatedness. In particular, an additive effect of stimulus quality and word frequency was found after related primes, and an interactive effect was found after unrelated primes. It was hypothesized that this pattern reflects an adaptive reliance on related prime information within the experimental context. In Experiment 2, related primes were eliminated from the list, and the interactive effects of stimulus quality and word frequency found following unrelated primes in Experiment 1 reverted to additive effects for the same unrelated prime conditions. The results are supportive of a flexible lexical processor that adapts to both local prime information and global list-wide context.     

Community recognition of objective and subjective characteristics of depression

Assessed knowledge of depression in a random sample of 527 community-living adults. Vignettes were presented which described a young or old protagonist with depressive symptoms. Respondents were asked to identify potential problems and possible solutions. A depression information measure followed. Results indicated that community residents were aware of many objective features of depression although they identified less information about treatment issues. Older respondents were least informed. Although there were no gender differences in objective knowledge, men were less likely to mention depression with regard to the vignettes. Suggestions for implementing more effective community interventions are discussed.     

Effects of objective and subjective account components on forgiving

The authors explored the effects of the components of a harm-doer's account of her transgression on the victims' emotional reactions to the transgression and to the character traits that she attributes to the harm-doer. Participants were 480 people whom the authors asked to imagine an incident in which they were harmed by the careless behavior of a friend. Subsequently, the authors offered participants an account of the harm-doer. In a 2 x 2 x 2 x 2 x 2 between-subjects design, the authors manipulated 5 account components: Admitting Fault, Admitting Damage, Expressing Remorse, Asking for Pardon, and Offering Compensation. The authors measured the participants' perceptions of these components. Results indicated that (a) the subjective perception of account components occurs schematically so that components are implicitly perceived without being objectively present, (b) objective components affect victims' reactions via subjective perceptions of these components, (c) personality factors (Irreconcilability, Interpersonal Trust, and Trait Anger) affect victims' reactions directly. Finally, certain configurations of account components are more effective than others. Specifically, asking for pardon had an effect on forgiving only when it was combined with an acknowledgment of the damage and a compensation offer. This result suggests that in this situation, the victim perceives a harm-doer's asking for pardon without the other components as an insincere apology.
