Color Emotion

It is estimated that inherited red-green color deficiency, which involves both the protan and deutan deficiency types, is common in men. For red-green defective observers, some reddish colors appear desaturated and brownish, unlike colors seen by normal observers. Despite its prevalence, few studies have investigated the effects that red-green color deficiency has on the psychological properties of colors (color emotions). The current study investigated the influence of red-green color deficiency on the following six color emotions: cleanliness, freshness, hardness, preference, warmth, and weight. Specifically, this study aimed to: (1) reveal differences between normal and red-green defective observers in rating patterns of six color emotions; (2) examine differences in color emotions related to the three cardinal channels in human color vision; and (3) explore relationships between color emotions and color naming behavior. Thirteen men and 10 women with normal vision and 13 men who were red-green defective performed both a color naming task and an emotion rating task with 32 colors from the Berkeley Color Project (BCP). Results revealed noticeable differences in the cleanliness and hardness ratings between the normal vision observers, particularly in women, and red-green defective observers, which appeared mainly for colors in the orange to cyan range, and in the preference and warmth ratings for colors with cyan and purple hues. Similarly, naming errors also mainly occurred in the cyan colors. A regression analysis that included the three cone-contrasts (i.e., red-green, blue-yellow, and luminance) as predictors significantly accounted for variability in color emotion ratings for the red-green defective observers as much as the normal individuals. Expressly, for warmth ratings, the weight of the red-green opponent channel was significantly lower in color defective observers than in normal participants. In addition, the analyses for individual warmth ratings in the red-green defective group revealed that luminance cone-contrast was a significant predictor in most red-green-defective individuals. Together, these results suggest that red-green defective observers tend to rely on the blue-yellow channel and luminance to compensate for the weak sensitivity of long- and medium-wavelength (L-M) cone-contrasts, when rating color warmth.

Specificity Effects

We examined the relative contribution of specific components of multidimensional anxiety to cognitive biases in the processing of threat-related information in three experiments. Attentional bias was assessed by the emotional Stroop word color-naming task, interpretative bias by an on-line inference processing task, and explicit memory bias by sensitivity (d') and response criterion (β) from word-recognition scores. Multiple regression analyses revealed, first, that phobic anxiety and evaluative anxiety predicted selective attention to physical- and ego-threat information, respectively; cognitive anxiety predicted selective attention to both types of threat. Second, phobic anxiety predicted inhibition of inferences related to physically threatening outcomes of ambiguous situations. And, third, evaluative anxiety predicted a response bias, rather than a genuine memory bias, in the reporting of presented and nonpresented ego-threat information. Other anxiety components, such as motor and physiological anxiety, or interpersonal and daily-routines anxiety made no specific contribution to any cognitive bias. Multidimensional anxiety measures are useful for detecting content-specificity effects in cognitive biases.

Reverse Pattern

The Stroop task has been employed to study automaticity or failures of selective attention for many years. The effect is known to be asymmetrical, with words affecting color naming but not vice versa. In the current work two auditory-visual Stroop-like tasks were devised in order to study the automaticity of pitch processing in both absolute pitch (AP) possessors and musically trained controls without AP (nAP). In the tone naming task, participants were asked to name the auditory tone while ignoring a visual note name. In the note naming task, participants were asked to read a note name while ignoring the auditory tone. The nAP group showed a significant congruency effect only in the tone naming task, whereas AP possessors showed the reverse pattern, with a significant congruency effect only in the note reading task. Thus, AP possessors were unable to ignore the auditory tone when asked to read the note, but were unaffected by the verbal note name when asked to label the auditory tone. The results suggest that pitch identification in participants endowed with AP ability is automatic and impossible to suppress.

Purpose: To compare the quality of life of senior first-year students with normal vision and myopia, and to explore the risk factors related to quality of life in students with myopia. Methods: In this study, 1103 senior first-year students were enrolled in ten high schools. These students were divided according to the diopter degree, with 916 myopia students and 187 normal vision students. Visual function indexes, such as naked eye vision, were measured and recorded, and social demographic indexes and the National Eye Institute 25-Item Visual Function Questionnaire (NEI VFQ-25) was used. The differences in quality of life between the two groups were compared. Multiple linear regression analysis was used to explore the possible risk factors for quality of life in myopia students. Results: In the NEI VFQ-25, the total quality of life scores of myopia students (77.06 ± 15.66) were lower than those of normal vision students (85.49 ± 12.37). The difference was statistically significant ( p = 0.007). In the correlation analysis, the total scores of quality of life in myopia students were positively correlated with wearing glasses ( p = 0.049), and were negatively correlated with study time ( p = 0.029). Multiple linear regression analysis showed that study time, wearing glasses and age were risk factors affecting quality of life in myopia students. Conclusion: Our results show that senior first-year myopia students have lower quality of life scores than students with normal vision. Study time, wearing glasses and age are risk factors for quality of life in senior first-year myopia students.

Interference Effects

Attention bias for alcohol has proved useful to distinguish people with a pathological consumption of people who do not, and dependents who are more likely to fall in consumption. The aim of this study was to validate the Spanish version of the Alcohol Stroop test, designed to evaluate attention biases for alcohol in alcohol-dependent patients. The sample was composed by 173 participants divided into 2 groups: 1) “Patients” (<em>n = </em>88) meeting criteria for alcohol dependence; and 2) “Control” (<em>n = </em>85) having a low risk for alcohol consumption, that completed the Stroop color naming Task (Classic Stroop), the Neutral Stroop test and the alcohol Stroop test. Statistically significant differences were found in the interference effects calculated for the Classic and Alcohol Stroop tests. Patients compared to control participants showed a higher interference effect for alcohol-related stimuli than for neutral stimuli. These effects were accounted by an attention bias for alcohol-related information in patients. ROC curves were calculated for the three interference effects, showing an area under the curve statistically significant in the Classic Stroop interference and the Alcohol Stroop interference. This study provides the validation of the Spanish version of the Alcohol Stroop test that allows to evaluate attention biases for alcohol stimuli in individuals with both pathologic alcohol consumption and alcohol dependence.

Naming Performance

In an unrestrained-choice color-naming task 26 males and 29 females responded to 21 colored chips from the Farnsworth-Munsell series. The females provided a significantly greater number of different color names for the chips than did the males. The data also showed that the leisure activities of the females were more color-dependent than those of the males. It is suggested that the observed sex differences in color-naming performance are learned differences in the expression of color appreciation.

Stimulation Technique

In some individuals, a visually presented letter or number automatically evokes the perception of a specific color, an experience known as color-grapheme synesthesia. It has been suggested that parietal binding mechanisms play a role in the phenomenon. We used a noninvasive stimulation technique, transcranial magnetic stimulation (TMS), to determine whether the posterior parietal lobe is critical for the integration of color and shape in color-grapheme synesthesia, as it appears to be for normal color-shape binding. Using a color-naming task with colored letters that were either congruent or incongruent with the synesthetic photism, we demonstrate that inhibition of the right posterior parietal lobe with repetitive TMS transiently attenuates synesthetic binding. These findings suggest that synesthesia (the induction of color from shape) relies on similar mechanisms as found in normal perception (where the perception of color is induced by wavelength).

Inhibition Studies

A three-part study investigates the effect of varying levels of interpolated task difficulty on recall, using a release from proactive inhibition methodology. It was hypothesized that difficulty of interpolated activity would affect recall levels. 544 college students served as Ss. Exp. 1 determined relative difficulty of four interpolated tasks, three of which are frequently used in proactive-inhibition studies, by measuring the amount of time necessary to complete each task. Utilizing a basic Peterson and Peterson format, Exp. 2 demonstrates that difficulty of the interpolated task will affect recall while not affecting the buildup of proactive inhibition. Again, incorporating the same format, Exp. 3 indicated the three commonly used distractor tasks, Stroop color-naming, counting backward, and color block-naming, can be used interchangeably; however, if the task is very easy (such as naming color blocks), recall may be so high that a ceiling effect is encountered. It is therefore suggested that researchers use one of the more difficult distractor tasks such as counting backward or the Stroop color-naming task for the prevention of rehearsal given the kind of Ss of the present study.
