Satisfaction at last: Evidence for the “satisfaction” hypothesis for multiple-target search errors

ABSTRACT

Multiple-target visual searches are susceptible to Subsequent Search Miss (SSM) errors—a reduced accuracy for target detection after a previous target has already been detected. SSM errors occur in critical searches (e.g., evaluations of radiographs and airport luggage x-rays), and have proven to be a stubborn problem. A few SSM theories have been offered, and here we investigate the “satisfaction” account: failing to completely finish a search after having found a first target. Accuracy on a multiple-target search task was compared to both how long participants spent searching after finding a first target and their target sensitivity in a separate vigilance task. Less time spent searching and poor vigilance predicted higher SSM error rates. These results suggest that observers who are more likely to miss a second target are less likely to thoroughly search after finding a first target, thus offering some of the first evidence for the “satisfaction” account.     

How satisfied are you with your job? Estimating the reliability of scores on a single‐item job satisfaction measure

Estimating the reliability of scores on single‐item measures can be difficult because commonly used internal consistency estimates of reliability cannot be calculated. When longitudinal data is available, statistical models can be used to decompose the variability in the latent variable at each wave into trait versus state variance. Then, reliability can be estimated as a ratio of the sum of the trait variance that is captured in repeated assessments over the total variance. The current study used latent trait‐state‐error models on a nine‐year longitudinal data (N = 5,003) to estimate the test–retest reliability of scores on a single‐item measure of job satisfaction. Results showed that job satisfaction scores were somewhat unreliable (r_xx = .49–.59) and amenable to change.     

Do the contents of visual working memory automatically influence attentional selection during visual search?

In many theories of cognition, researchers propose that working memory and perception operate interactively. For example, in previous studies researchers have suggested that sensory inputs matching the contents of working memory will have an automatic advantage in the competition for processing resources. The authors tested this hypothesis by requiring observers to perform a visual search task while concurrently maintaining object representations in visual working memory. The hypothesis that working memory activation produces a simple but uncontrollable bias signal leads to the prediction that items matching the contents of working memory will automatically capture attention. However, no evidence for automatic attentional capture was obtained; instead, the participants avoided attending to these items. Thus, the contents of working memory can be used in a flexible manner for facilitation or inhibition of processing.     

Misleading contextual cues: How do they affect visual search?

Contextual cueing occurs when repetitions of the distractor configuration are implicitly learned. This implicit learning leads to faster search times in repeated displays. Here, we investigated how search adapts to a change of the target location in old displays from a consistent location in the learning phase to a consistent new location in the transfer phase. In agreement with the literature, contextual cueing was accompanied by fewer fixations, a more efficient scan path and, specifically, an earlier onset of a monotonic gaze approach phase towards the target location in repeated displays. When the repeated context was no longer predictive of the old target location, search times and number of fixations for old displays increased to the level of novel displays. Along with this, scan paths for old and new displays became equally efficient. After the target location change, there was a bias of exploration towards the old target location, which soon disappeared. Thus, change of implicitly learned spatial relations between target and distractor configuration eliminated the advantageous effects of contextual cueing, but did not lead to a lasting impairment of search in repeated displays relative to novel displays.     

How satisfied are patients with the ministry of chaplains?

The author describes the importance of chaplaincy departments conducting periodic patient satisfaction studies and provides quantitative results from 1440 patients discharged from one of 14 U.S. general hospitals. Patients expressed the most satisfaction in response to the item, "The chaplain seemed to be a person of spiritual sensitivity." The results also suggest the characteristics of patients who appear most responsive to this ministry.     

Emotional devaluation of distracting patterns and faces: a consequence of attentional inhibition during visual search?

Visual search has been studied extensively, yet little is known about how its constituent processes affect subsequent emotional evaluation of searched-for and searched-through items. In 3 experiments, the authors asked observers to locate a colored pattern or tinted face in an array of other patterns or faces. Shortly thereafter, either the target or a distractor was rated on an emotional scale (patterns, cheerfulness; faces, trustworthiness). In general, distractors were rated more negatively than targets. Moreover, distractors presented near the target during search were rated significantly more negatively than those presented far from the target. Target-distractor proximity affected distractor ratings following both simple-feature and difficult-conjunction search, even when items appeared at different locations during evaluation than during search and when faces previously tinted during search were presented in grayscale at evaluation. An attentional inhibition account is offered to explain these effects of attention on emotional evaluation.     

Category effects in visual search: A failure to replicate the “oh-zero” phenomenon

In the experiment of Jonides and Gleitman (1972), subjects searched displays of digits or letters for single, specified digit or letter targets. The slope of the function relating reaction time to display size was positive (mean=25 msec/item) if target and nontargets belonged to the same alphanumeric category (within-category search), but zero if target and nontargets belonged to different categories (between-category search). This held even for the target O, whose categorical relationship to nontargets was determined entirely by the name it was given. In the present paper, two attempted replications are reported, one as close as practically possible. For the unambiguous targets A, Z, 2, and 4, slopes were greater in within-category search than in between-category search, but positive and very variable in both cases. For the ambiguous target O, slopes were identical in within-category and between-category search, and again positive. The results suggest that with single, specified targets, differences between within-category and between-category search may be due entirely to variation in the average physical resemblance between target and nontargets. In line with previous findings, they show that one cannot characterize within-category search as generally “serial” and between-category search as generally “parallel.”     

Adjustment to and satisfaction with retirement: two of a kind?

Multiactor panel data on 778 Dutch employees were used to examine adjustment to and satisfaction with retirement. Regression analyses revealed that adjustment and satisfaction are related, but not identical. Adjustment problems arise from preretirement anxiety about the social consequences of retirement and from a lack of control over the decision. Retirement satisfaction is primarily related to the individual's access to key resources: finances, health, and the marital relationship. The study shows that the retirement transition is multidimensional. The transition involves two developmental challenges: adjustment to the loss of the work role and the social ties of work, and the development of a satisfactory postretirement lifestyle. Making a distinction between these two aspects of the retirement experience is important for a better understanding of the psychological process following retirement.     

Effects of type of responding on memory/visual search: Responding just “yes” or just “no” can lead to inflexible performance

Interactions of stimulus consistency and type of responding were examined during perceptual learning. Subjects performed hybrid memory-visual search tasks over extended consistent and varied mapping practice. Response conditions required subjects to respond to both the presence and absence of a target, only when a target was present or only when a target was not present. After training, the subjects were transferred to a different response condition. The results indicate that: (1) performance on search tasks with stimuli that are variably mapped show no qualitative changes attributable to manipulation of response format; (2) improvement due to consistent mapping (CM) practice is attenuated in the no-only response condition; (3) yes-only CM training attenuates the subjects ability to transfer to no-only responding; and (4) yes/no CM training leads to the greatest improvement and transfer when compared with other responding conditions. The practice and transfer data support and extend previous research investigating effects of response set in memory/visual search and help to delineate factors that facilitate or inhibit reduction of load effects in memory and visual search.     

In search of the optimal measure of awareness: Discrete or continuous?

Studies of perceptual awareness require sensitive measures reflecting subjective judgments of visibility. Two scales have been proposed for this purpose: the Continuous Scale (CS) and the Perceptual Awareness Scale (PAS). Here we compare the scales in the context of the Gabor patch orientation discrimination task and propose a Continuous Perceptual Awareness Scale (C-PAS) that aims to combine their advantages. The results of the study shown no differences in sensitivity between the scales. However, we observed differences between the scales in awareness ratings frequencies and accuracy associated with the lowest ratings. We concluded that visibility ratings are often biased, and thus, the scale sensitivity may not be optimal. Furthermore, based on the additional analyses, we argued that there is an advantage of using C-PAS over CS. The scale allows to use an additional variability of judgment within PAS categories and thus it may enable more fine-grained measurement of visibility at near-threshold conditions.     

Implicit learning: A way to improve visual search in spatial neglect?

Studies have shown that neglect patients are able to use stimulus regularities to orient faster toward the neglected side, without necessarily being aware of that information, or at the very least without being able to verbalize their knowledge. In order to better control for the involvement of explicit processes, the present study sought to test neglect patients’ ability to detect more complex associations between stimuli using tasks similar to those used in implicit learning studies. Our results demonstrate that neglect patients had difficulties implicitly learning complex associations, contrary to what we found with controls. The possible influence of attentional and working memory impairments are discussed.

Inhibitory guidance in visual search: The case of movement–form conjunctions

We used a probe-dot procedure to examine the roles of excitatory attentional guidance and distractor suppression in search for movement-form conjunctions. Participants in Experiment?1 completed a conjunction (moving X amongst moving Os and static Xs) and two single-feature (moving X amongst moving Os, and static X amongst static Os) conditions. "Active" participants searched for the target, whereas "passive" participants viewed the displays without responding. Subsequently, both groups located (left or right) a probe dot appearing in either an occupied or an unoccupied location. In the conjunction condition, the active group located probes presented on static distractors more slowly than probes presented on moving distractors, reversing the direction of the difference found within the passive group. This disadvantage for probes on static items was much stronger in conjunction than in single-feature search. The same pattern of results was replicated in Experiment?2, which used a go/no-go procedure. Experiment?3 extended the go/no-go procedure to the case of search for a static target and revealed increased probe localisation times as a consequence of active search, primarily for probes on moving distractor items. The results demonstrated attentional guidance by inhibition of distractors in conjunction search.     

“Getting to Know”: Exploring How Urban African American Women Conceptualize Safer and Risky Sexual Behaviors

The surge in the rate of the Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS) cases continues to be most prevalent for African American women between the ages of 18 and 29, with heterosexual transmission remaining the primary cause of HIV spread for this population. The high rates of HIV/AIDS among African American women continue to emphasize the need for understanding how members of this population conceptualize sexual safety and risk. A qualitative research study using grounded theory methods was conducted to explore how African American women define safer and risky sexual behaviors. Interviews were conducted with 14 African American women between the ages of 18 and 29. The study findings suggest that African American women’s definitions of safer and risky sexual behaviors, while in a consensual sexual relationship, are consistently influenced by sex partner type. The information garnered from this study can help inform the development of HIV prevention strategies, health education, counseling and reproductive health services that support African American women’s wellness.     

Preattentive face processing: What do visual search experiments with schematic faces tell us?

In recent research, several experiments have tested a preattentive threat-advantage hypothesis that threatening or negative faces can be discriminated preattentively, by using the visual search paradigm. However, supporting evidence is nonuniform, giving rise to the suspicion that stimulus factors rather than the stimuli's category of facial threat versus friendliness are responsible for sporadic demonstrations of a threat advantage. However, it is also possible that differences in experimental procedure contribute to the heterogeneous results. To test this possibility I selected examples from the past literature and presented them within the same constant experimental setting. I found a consistent advantage for negative face targets among positive face distractors with all stimulus pairs. Search slopes, however, mostly revealed inefficient search, questioning the preattentive discrimination of facial affect.     

Inhibition of return and visual search: how many separate loci are inhibited?

Using a novel sequential visual search paradigm Danziger, Kingstone, and Snyder (1998) demonstrated that inhibition of return (IOR) can reside at three spatial locations. In the present study, we extended the work of Danziger et al. by investigating whether there is a limit to the number of locations that can be inhibited in a sequential visual search task. Our study revealed that IOR can be measured at a minimum of five locations. The magnitude of the IOR effect was largest at the most recently searched location and declined from there in an approximately linear fashion. Two models that can account for our data are presented.
