The Baggies collected 14 points from their opening seven Barclays Premier League matches to give Clarke an impressive baptism to his first managerial role.
They have since suffered injury-time setbacks against Manchester City and then Newcastle.
But Clarke has faith in his players to rise to the challenge and halt their mini slump if they show the same sort of form in tomorrow [Monday] evening's home encounter with Southampton.
He said: "It's going to be something different for us. We are suddenly in a situation we haven't found ourselves in before in having lost a couple of games.
"People maybe are looking at us a little bit so there is a question to be answered.
"But the lads have played well and that is the message we have tried to give the players to take forward into the next game.
"We have told them that if they continue to play as they have against two really good teams, and as long as the performance levels stays the same, then the results will follow."
When asked if teams were showing Albion more respect, Clarke said: "I think that is probably right. People have looked at the start we've had.
"Newcastle paid us a big compliment last week when they matched us up and went system for system. They looked at us, felt we could cause them a problem and they tried to nullify that.
"They will be delighted it worked for them because they got the result but we got the performance and the confidence will not have been affected.
"It is about results but you find in football results and performances tend to go hand in hand. If you are playing well, the results will follow."
Clarke has plenty of respect for Saints and their manager Nigel Adkins, who has led the club to successive promotions, despite a difficult start to the campaign.
He said: "Nigel has had two successive promotions and done a great job for the club.
"Unfortunately the game now is a results-driven industry and you don't get as long sometimes as you deserve to get.
"But Southampton have had some good performances. I've seen them on a number of occasions this season.
"They are a team we will treat with 100 per cent respect. We expect a really difficult game.
"Nigel's teams always like to pass the ball. They are dangerous, can create chances and score goals.
"It gets highlighted that they have conceded a few as well and that's up to us to try and exploit but we have to make sure we defend very well.
"If we do that, we have a chance of getting a good result."
West Brom skipper Chris Brunt and defender Billy Jones have recovered from hamstring and knee injuries respectively and are in contention to face the Saints.
Clarke is also optimistic striker Shane Long will have shaken off the hamstring injury which led to his non-inclusion in the Republic of Ireland squad for the forthcoming friendly with Greece.
