Cognitive Alteration of Feeling States: Historical Background

Within the scientific community there is a growing awareness and acceptance of the notion that people do not exist only in a world of physical forces and events. A person's perception of the world in which they live in a world is also defined by their own perceptions, experiences, and biases. In other words, a person responds and reacts, not only to objective or experimenter-defined stimuli, but also to his or her apperceptions and subjectively defined stimuli.     

Biblical narratives for positive psychology and suicide prevention: an evidence supported approach

Suicide is the ultimate outcome of a tragic view of life that is prevalent in ancient Greek writings. Indeed, over 16 suicides and self-mutilations can be found in the 26 surviving tragedies of Sophocles and Euripides. In contrast, only six suicides can be found in the Hebrew Scriptures, and only one suicide in the Christian Scriptures. In addition, the Hebrew Scriptures present numerous suicide-prevention narratives that are psychologically instructive. This paper examines evidence regarding seven risk factors for suicide and contrasts Greek and Biblical narratives to underscore the clinical and theoretical utility of the Biblical approach: (1) Feeling isolated and ignored; (2) Feeling one’s life is meaningless; (3) Feeling exiled from one’s home or homeland; (4) Feeling unable to be oneself with others; (5) Feeling alone in one’s life mission; (6) Feeling abandoned by one’s child; and (7) Feeling doomed by a dysfunctional family of origin.     

A quaternary temperament model and defense cluster preferences

A quaternary model of temperament constructed from orthogonal axes defined by Extraversion-Introversion and Thinking-Feeling resulted in four groups: Introverted Thinking, Introverted Feeling, Extraverted Thinking, and Extraverted Feeling. Hypothesized relationships between quaternary groups and defense cluster preferences were tested by giving 158 female college students the Myers-Briggs Type Indicator and the Defense Mechanisms Inventory. There was little support for hypothesized relationships between the quaternary model and defense preferences. The only hypothesized significant group difference showed the Extraverted Feeling group recording a greater preference for the Reversal defense cluster than the Introverted Feeling group.     

The cognitive implications of asymmetric color generalization in honeybees

Generalization occurs when a conditioned response formed to one stimulus is also elicited by other stimuli which have not been used in the course of conditioning. Here, we studied color generalization in honeybees Apis mellifera trained to two rewarded colors, S₁+ and S₂+. After training, bees were tested with non-rewarded novel stimuli, which lay between the trained stimuli in a honeybee color space (Int) or outside the range defined by the trained stimuli (E ₁ and E ₂). We analyzed whether bees interpolated their choice to Int and/or extrapolated it to E ₁ and E ₂. We compared the performances of the group trained with S₁+ and S₂+ to those of control groups trained only with S₁+ or S₂+. Bees trained with S₁+ and S₂+ responded similarly and highly to all test stimuli. These results do not allow discerning between generalization models based on the presence of interpolation and/or extrapolation. Nevertheless, bee’s performance was consistent with a linear summation of the two generalization gradients generated by S₁+ and S₂+, respectively. These gradients were asymmetric because control bees responded to the test stimuli as if these belonged to different similarity classes in spite of the fact that they had similar perceptual distances separating them. Stimuli treated as similar were located in the same half of the color spaces, whereas stimuli treated as different were located in opposite halves. Our results suggest that color categories could exist in honeybees and may underlie the performance of the control groups. Under this assumption, color categories would be also present in simpler nervous systems, and would not require factors such as language to be expressed.     

Filtering by movement in visual search.

Search for a target defined by a conjunction of movement and form (e.g., an X moving up in a display of intermingled Os moving up and stationary Xs) is parallel. This result is also found if (a) the moving Os and target X move in unpredictable directions so that the moving stimuli do not form a clear perceptual group or (b) the nontarget Xs also move but in a known, different direction from the Os and target X. In contrast, search is slow and serial if the target may be unpredictably among either moving or stationary stimuli. These results suggest that a component of the visual system operates as a movement filter that can direct attention to stimuli with a common movement characteristic. The filtering cue can be moving (vs. stationary), or movement in 1 particular direction. The results do not support the view that attention can only be directed to groups defined by common fate.     

IV. Logic and truth‐finding in society and sociology

The question of sociological truth‐finding is posed in the light of the view that logical formalizations, along with other arguments, only acquire relevance in illocutionary contexts, where it is not so much the abstract correctness of a sentence as the stating of it that counts. In order to become a counterfactual an argument requires its antecedent to be recognized as being contrary to the ‘facts’. To this extent there is a clear link with ‘reality’ or with a view of the world that is taken as factually given. Social science develops on the basis not only of generalizations but also of historical facts and political requirements. The question arises: in terms of what world‐view or purpose can we unambiguously declare a conditional to be a counterfactual ‐ and a significant or non‐trivial one at that? Further, can Elster's clarifications help identify political agents and the proper entities within and through which political action is performed? Finally, the problem‐solving capacity of the concept of closeness of one possible world to another or to the actual world, especially with regard to counterfactuals and causality, is questioned.     

A Study of Belief in the Accuracy of Newspaper Reports

An examination of the relationship of scores on Siegel's Manifest Hostility Scale (MHS) to Verbal Hostility, Fantasy Hostility, and Hostile Feeling responses to cartoon situations was undertaken, while controlling for sex of subject, sex of experimenter, and the social desirability (So-R) and ego strength/defensiveness (K) scales of the MMPI. MHS scores were significantly related to the three modes of hostility response, while sex of subject and sex of experimenter were not. Adjustment of the dependent variable means for So-R did not cancel MHS effects on Verbal or Fantasy Hostility, but adjustment for K cancelled the significant relationship between MHS scores and Fantasy Hostility and Hostile Feeling responses. Covariation of both K and So-R out of Verbal Hostility cancelled its relationship to MHS scores. Ego strength/defensiveness thus may be more significantly related to hostile responding than social desirability.     

The effect of comparative context on evaluative conditioning

Evaluative conditioning (EC) is a change in the evaluation of a stimulus after the stimulus co-occurred with affective stimuli. The present research examined whether EC of one stimulus depends also on the co-occurrence of another stimulus with positive or negative stimuli. We paired two target people with affective stimuli. We found that a person who appeared eight times with positive stimuli and eight times with negative stimuli was liked more when the other person appeared always (16 times) with negative stimuli than when the other person appeared always with positive stimuli. The manipulation did not change the US evaluation or the general standard on the value dimension of what a positive or negative stimulus is. We suggest that like other evaluative traits (e.g., evil, pretty) co-occurrence with affective stimuli is sensitive to temporary standards. The manipulation changed the standard of what co-occurrence with affective stimuli is considered positive versus negative.     

Temporal generalization under time pressure in humans

In two experiments, participants performed a temporal generalization task in which they were asked to decide whether or not the durations of comparison stimuli were different from those of standard stimuli (750 ms, 1,000 ms, or 1,250 ms). One half of the participants was instructed to respond as quickly as possible, while the other half received no instruction concerning the speed of response. The relationship between stimulus duration and the time of response and the effect of time pressure on duration discrimination were examined. Response time increased as a linear function of the duration of the to-be-judged stimuli until a certain instant, which was defined as T ₂ = s/(1 – b), where s refers to the internal representation of the standard duration and b to the decision threshold. Moreover, the participants systematically overestimated the presented intervals if they were asked to respond as fast as possible when the standard duration was either 1,000 ms or 1,250 ms, but not when the standard duration was 750 ms.     

An inversion effect modified by expertise in capuchin monkeys

The face inversion effect may be defined as the general impairment in recognition that occurs when faces are rotated 180°. This phenomenon seems particularly strong for faces as opposed to other objects and is often used as a marker of a specialized face-processing mechanism. Four brown capuchin monkeys (Cebus apella) were tested on their ability to discriminate several classes of facial and non-facial stimuli presented in both their upright and inverted orientations in an oddity task. Results revealed significantly better performance on upright than inverted presentations of capuchin and human face stimuli, but not on chimpanzee faces or automobiles. These data support previous studies in humans and other primates suggesting that the inversion effect occurs for stimuli for which subjects have developed an expertise.     

The modulation of stimulus structure on visual field asymmetry effects: The case of Chinese character recognition

Recent research suggests that visual field (VF) asymmetry effects in visual recognition may be influenced by information distribution within the stimuli for the recognition task in addition to hemispheric processing differences: Stimuli with more information on the left have a right VF (RVF) advantage because the left part is closer to the centre, where the highest visual acuity is obtained. It remains unclear whether visual complexity distribution of the stimuli also has similar modulation effects. Here we used Chinese characters with contrasting structures—left-heavy, symmetric, and right-heavy, in terms of either visual complexity of components or information distribution defined by location of the phonetic component—and examined participants' naming performance. We found that left-heavy characters had the largest RVF advantage, followed by symmetric and right-heavy characters; this effect was only observed in characters that contrasted in information distribution, in which information for pronunciation was skewed to the phonetic component, but not in those that contrasted only in visual complexity distribution and had no phonetic component. This result provides strong evidence for the influence of information distribution within the stimuli on VF asymmetry effects; in contrast, visual complexity distribution within the stimuli does not have similar modulation effects.     

Unimodal and crossmodal effects of endogenous attention to visual and auditory motion

Three experiments were conducted examining unimodal and crossmodal effects of attention to motion. Horizontally moving sounds and dot patterns were presented and participants’ task was to discriminate their motion speed or whether they were presented with a brief gap. In Experiments 1 and 2, stimuli of one modality and of one direction were presented with a higher probability ( p = .7) than other stimuli. Sounds and dot patterns moving in the expected direction were discriminated faster than stimuli moving in the unexpected direction. In Experiment 3, participants had to respond only to stimuli moving in one direction within the primary modality, but to all stimuli regardless of their direction within the rarer secondary modality. Stimuli of the secondary modality moving in the attended direction were discriminated faster than were oppositely moving stimuli. Results suggest that attending to the direction of motion affects perception within vision and audition, but also across modalities.     

Moving and looming stimuli capture attention

Attention capture is often operationally defined as speeded search performance when an otherwise nonpredictive stimulus happens to be the target of a visual search. That is, if a stimulus captures attention, it should be searched with priority even when it is irrelevant to the task. Given this definition, only the abrupt appearance of a new object (see, e.g., Jonides & Yantis, 1988) and one type of luminance contrast change (Enns, Austen, Di Lollo, Rauschenberger, & Yantis, 2001) have been shown to strongly capture attention. We show that translating and looming stimuli also capture attention. This phenomenon does not occur for all dynamic events: We also show that receding stimuli do not attract attention. Although the sorts of dynamic events that capture attention do not fit neatly into a single category, we speculate that stimuli that signal potentially behaviorally urgent events are more likely to receive attentional priority.     

A dynamic context model of interactive behavior

A dynamic context model of interactive behavior was developed to explain results from two experiments that tested the effects of interaction costs on encoding strategies, cognitive representations, and response selection processes in a decision-making and a judgment task. The model assumes that the dynamic context defined by the mixes of internal and external representations and processes are sensitive to the interaction cost imposed by the task environment. The model predicts that changes in the dynamic context may lead to systematic biases in cognitive representations and processes that eventually influence decision-making and judgment outcomes. Consistent with the predictions by the model, results from the experiments showed that as interaction costs increased, encoding strategies and cognitive representations shifted from perception-based to memory-based. Memory-based comparisons of the stimuli enhanced the similarity and dominance effects, and led to stronger systematic biases in response outcomes in a choice task. However, in a judgment task, memory-based representations enhanced only the dominance effects. Results suggested that systematic response biases in the dominance context were caused by biases in the cognitive representations of the stimuli, but response biases in the similarity context were caused by biases in the comparison process induced by the choice task. Results suggest that changes in interaction costs not only change whether information was assessed from the external world or from memory but also introduce systematic biases in the cognitive representation of the information, which act as biased inputs to the subsequent decision-making and judgment processes. Results are consistent with the idea of interactive cognition, which proposes that representations and processes are contingent on the dynamic context defined by the information flow between the external task environment and internal cognition.     

The Communicative Experience: Between Inexpressibile and Elusive

This is a commentary on Cornejo’s Intersubjectivity as co-phenomenology: from the holism to the being-in-the-world-with-others, co-phenomenology, in which meaning is defined as a construal of phenomenological experience, not an individual creation, but rather an intersubjective one. In this paper the basic question is how language expresses the world and things and, consequently, what vision of the world is expressed by language and what relationship it creates with the real. Language lives for and by this constant aspiration to say the inexpressible and it tries to express the driving inner movement of the real through references and interlacing, by multiplying the relational threads of meanings. For example, the phonetic gesture performs for the speaker and his listener a certain structuring of experience, a certain modulation of existence. This is a communicative dimension in which meaning is always a process. It is the situation of co-feeling between subjects, in which understanding is achieved, as defined by Cornejo in his essay. Words, vowels, phonemes from this analysis are not only the conceptual and the final sense of words, but also their emotional sense, are ways to sing the world and they represent the emotional essence.

Categorization of visual stimuli in the honeybee Apis mellifera

Categorization refers to the classification of perceptual input into defined functional groups. We present and discuss evidence suggesting that stimulus categorization can also be found in an invertebrate, the honeybee Apis mellifera, thus underlining the generality across species of this cognitive process. Honeybees show positive transfer of appropriate responding from a trained to a novel set of visual stimuli. Such a transfer was demonstrated for specific isolated features such as symmetry or orientation, but also for assemblies (layouts) of features. Although transfer from training to novel stimuli can be achieved by stimulus generalization of the training stimuli, most of these transfer tests involved clearly distinguishable stimuli for which generalization would be reduced. Though in most cases specific experimental controls such as stimulus balance and discriminability are still required, it seems appropriate to characterize the performance of honeybees as reflecting categorization. Further experiments should address the issue of which categorization theory accounts better for the visual performances of honeybees.This contribution is part of the special issue “Animal Logics” (Watanabe and Huber 2006).     

Memory bias for threatening information related to anxiety: an updated meta-analytic review

The evidence for an anxiety-related memory bias is contradictory. We compiled 171 articles published until October 2016 including a group with clinical or subclinical anxiety and a control group in tasks involving implicit or explicit memory using threatening stimuli. There was an anxiety-related memory bias in free recall tasks, but it was not observed in another memory task. The between-groups differences showed that the anxious group recalled more threatening stimuli than the control group (d?=?0.321). When we compared the group differences (anxious vs. control participants) in the within-groups effect (threatening vs. neutral stimuli), a moderate effect size emerged (d_bw?=?0.714). This anxiety-related memory bias was observed with shallow processing, that is consistent with attentional biases related to anxiety. There was also evidence that high-anxious persons recall fewer positive stimuli. Future research is needed to investigate whether this result is a memory or encoding bias and explore other moderator variables.     

A New Measure of Hallucinatory States and a Discussion of REM Sleep Dreaming as a Virtual Laboratory for the Rehearsal of Embodied Cognition

Hallucinatory states are experienced not only in connection with drugs and psychopathologies but occur naturally and spontaneously across the human circadian cycle: Our nightly dreams bring multimodal experiences in the absence of adequate external stimuli. The current study proposes a new, tighter measure of these hallucinatory states: Sleep onset, REM sleep, and non‐REM sleep are shown to differ with regard to (a) motor imagery indicating interactions with a rich imaginative world, and (b) cognitive agency that could enable sleepers to recognize their hallucinatory state. Mentation reports from the different states were analysed quantitatively with regard to two grammatical–semantic constructs, motor agency and cognitive agency. The present results support earlier physiological and psychological evidence in revealing a decline in cognitive functions and an increase in simulated interactions with a hallucinatory world, en route to normal REM sleep. This leads us to introduce the hypothesis that REM sleep, which exhibits remarkably high levels of (simulated) sensorimotor processes, may have evolved to serve as a virtual laboratory for the development and rehearsal of embodied cognition. The new measure of hallucinatory states presented here may also hold implications for the study of executive functions and (meta‐)cognitions, which might be interesting, for example, for the investigation of lucid dreaming.     

Positive post‐disaster images: A daydream machine?

This study explores the impact of post‐earthquake images inserted in a vigilance task, in terms of performance, self‐reports of task‐focus, and cerebral activity using functional near‐infrared spectroscopy (fNIRS). Vigilance tasks present a sequence of stimuli in which only a few are pre‐designated critical or target stimuli requiring an overt response from the participant. Seventy‐one residents participated (51 women, 20 men) by taking part in a vigilance task with task‐irrelevant images inserted in the sequence. There were three conditions consisting positive (emotive inducing), negative (emotive inducing), and control (devoid of meaning) images embedded in the vigilance task to assess possible impacts on vigilance performance. The images were obtained through crowdsourcing and represented parts of the city 3–4 years post‐earthquake. Task performance was assessed with signal detection theory metrics of sensitivity A’ and bias β’’. This enables the separation of an individual's ability to accurately discriminate critical signals from non‐critical stimuli (sensitivity) and shifts in their willingness to respond to any stimuli whether critical or not (bias). Individuals viewing the positive images, relating to progress, rebuild, or aesthetic aspects within the city, had a more conservative response bias (they responded less to both rare critical and distractor stimuli) than those in the other conditions. These individuals also reported lower task‐focus, as would be expected. However, contrary to expectations, indicators of cerebral activity (fNIRS) did not differ significantly between the experimental groups. These results, when combined, suggest that mind wandering events may be being generated when exposed to positive post‐earthquake images.
